The Future That Hasn't Arrived

jonerik writes "MSNBC has this article on an exhibit starting this week at Philadelphia's Lost Highways Archive and Research Library. Entitled Radebaugh: The Future We Were Promised, the exhibit focuses on the artwork of the elusive A.C. Radebaugh, a commercial illustrator whose works promised us a glittering, shiny tomorrow from the '30s to the '50s; a helicopter in every garage, massive streamlined cars, vacations on Mars - in short, pretty much everything we didn't get. The exhibit collects examples from Radebaugh's portfolio, auto designs for Chrysler, DoSoto, and Dodge, ads, and 'Closer Than We Think!,' a syndicated weekly comic strip drawn by Radebaugh. I want my jetpack, dammit!"

    When did we start thinking about the future so much? Did people in the middle ages, for example, ever think much past the end of their own lives? I'm guessing they did, but I don't think they could have imagined a world much different than their own.

    When we think of the future, we almost always think of technology. We think of starships and other things that are waaaaaay far off, so maybe the industrial revolution spurred this new way of thinking. Anyway, I'm justing typing randomly. I'll bet some historian will tell me I'm totally wrong.

          Well, it has, in absolute terms, but not in relative terms. The problem is that human psychology makes us view things using relative metrics instead of absolute ones. If you earn a 20% raise this year, but all your friends earn 100% raises, do you feel richer or poorer compared to last year?

          If you want to have a 1950s comfortable standard of living regarding possessions, health care, entertainment, food, etc. you can do so by working far fewer hours than a 1950s human had to. But if you want a 2000s standard of living... ah, then you still have to work, or otherwise procure income. But at least work tends to be less menial and physically taxing than it did in the 1950s, on the average at least.

          It's a question of whether you measure standard of living by absolute standards or relative ones. No matter what the technology level, it will be always true (in capitalist societies, anyway) that someone who works hard will, on the average, earn more than someone who works little at the same level of technology. So of course the idle will never win ... in relative terms. But if you view things in absolute terms, the idle American today can live far more comfortably than the average hard-working American in the 1950s. (The same is even true of the third world; a citizen of country X today has a more comfortable existence than a citizen of X in the 1950s, in almost all cases - calorie intake has more or less doubled, for instance, and life expectancy extended by a decade or more. Again, in relative terms the poor countries of 2000 will be behind the rich countries of 2000, but they can certainly be comparable with the rich countries of 1950 in many absolute, objective metrics.).

          Nevertheless, I do agree with you on one point - there is more to life than the rat race. But you are free at any time to downshift and live a comfortable and leisuirely life, and viewed in absolute terms one has far more capability to do so now than in the past. It's only the relative viewpoint which seems to suggest that one cannot "afford" to be idle.

      In the middle ages, the world would have seemed to be utterly unchanged - for the previous few centuries at least. In that situation, why would you ever expect change? Predicting a very different future back then would have been just silly.

      We have seen such spectacular growth in just about every part of life in perhaps two lifetimes - we now see life in terms of change. Shall I buy an ATI Radion 9700 graphics card - or should I wait a few months and get an nVidia GeForceFX? (Oh - wait...bad example!)

      I expect change - I *rely* on change. Predicting the future is now a survival trait and humans are nothing if not adaptable when it comes to surviving.

      We have codified change into things like Moores Law. We are suprised and perhaps even a little fearful when things don't change fast enough (see dozens of /. articles about the immenent failure of Moores Law for example).

      Actually, I think what's most interesting about this exhibit is just how LITTLE change he predicted. Cars still have enormous chrome fins - people still dress exactly the same as they did in the 30's, 40's and 50's - everyone still commutes to work. For us, looking at these, we see a weird mix of antique design with machines and buildings that we still havn't managed to engineer.

      "When did we start thinking about the future so much?"
      Hmmm probably right about the time we started to feel the pressure of day-to-day life. We're pretty good at imagining the good parts of the future and pretty bad at imagining the complications. In other words, a long long long long time ago.

      Certainly we were looking to the future long before the middle ages. Christianity, for example, is based on the hope for a better future; specifically on the hope that a saviour will change things for the better. Apparently there was a common belief that life could be better.

      "When we think of the future, we almost always think of technology ... so maybe the industrial revolution spurred this new way of thinking."
      It isn't really a different way of thinking, it's just that technology has largely replaced magic and other nebulous things as the future improvent of choice. I think that shift to technology likely did happen during the industrial revolution because that is the time that technological advances started coming at a rate noticable to the common person.

      I find it interesting that we continue to look to the future for improvement in our day to day lives, even though technological improvement has almost exclusively resulted in a more complicated life style, the oposite of what we hope for. It always lets us down at the most basic level.

    I am assuming the root of the matter is the disparity between what was predicted in art (science fiction) and what actually happened. I always felt there was too much of a preoccupation with space travel in the past. I guess this makes sense, given the Space Race took up a good amount of people's attention. However, there were two areas that were overlooked: The Internet and advancements in genetics. Both caught the forward-thinkers of the past by surprise.

    There were many assumptions of huge talking robots, but not as many about the computers we have today. Our computers are not as powerful, but they're a commodity, available to everybody. Also, cloning was a pipe dream; something to happen in the year 2500 or whatever. And here we are, playing around with cloning cats.

    It's not so bad, really, though I could use a good mail-order robobabe right about now.

      One of the common mistakes when futurists try to make guesses about the nature of society a few decades from now is that they presume that trends that have been true will continue to be true. There are many examples of this.

      During the 50s and 60s, there was a steep up ramp in energy consumption. Because of this, there were many dire predictions in the 70s that we would soon run out of energy. But the steep curve leveled off and the "energy crisis" never happened.

      From the late 1800s to the 1960s, our ability to go faster and farther was also on a steep upward curve. Futurists naturally extending this trend assumed that travel to the planets would become commonplace and that personal air transport would soon become a cheaply available transport solution.

      From the early 1900s to the 1960s there was great increase in leisure time. Some futurists postulated a future existence where only a few people worked and most just goofed off.

      From the 1800s to the 1960s there was a tremendous improvement in using machines to replace humans when it came to various tasks. Again, it was natural to extend this trend to the point that robots manufactured most of the goods consumed by society. Also, during this period there was a large growth in household convenience devices. Extending this trend, it was natural to assume that there would soon be robots that performed all your housework,

      Sometimes it is more interesting to examine what was missed. For most of the modern age up to the 1970s, there was not a great improvement in the speed (and quantity) in which written communication was delivered. It still took at least a few days for mail to arrive and international mail still could be a matter of weeks. In order to disseminate information (such as research), large mass printings had to be created and distributed in a very manual way. TV improved the communication process somewhat, but for information with a more limited audience, the basic infrastructure and approach for delivery had not changed for quite some time. That is why "email" and "website" was not on the minds of most futurists.

      Also during this period, the mechanisms by which numeric and financial calculations were performed did not change much. It was both expensive to do the calculations and expensive to disseminate the results (My childhood was still in the era where we had to consult large logarithm tables to assist in doing simple arithmetic - something they were doing back in the 1700s). Thus it was not a natural presumption that computers could manage all the details of various financial transactions. In particular, EBay and PayPal were not envisioned.

      So my challenge to futurists is to look a little deeper and try to anticipate changes that are not already occurring and extrapolate those. But that is not happening. Every futurist these days seems to be obsessed with small-computerized gadgets linked in high-speed communication networks that allow users to access broadband entertainment. A completely natural but probably mistaken prediction based on current trends.

    I remember when I was a kid(think I was 3), I saw a 2 page magazine spread featuring a car which could convert into an airplane. The caption was something like "Soon you'll be able to avoid traffic jams by flying over them." ... "this car can convert to an airplane in 15 minutes".

    I don't remember the manufacturer or anything. I think this was sometime around 1969 or 70.

    Instead, we have computers literally millions of times faster than anyone imagined we'd have. Read some old sci-fi, and notice how the authors tend to make reference to people plotting the navigations by hand because it'd be too complicated for a computer?

    First off, companies have to invest in and develop such shiny stuff, and then the public has to lay down their hard earned cash. That is the biggest reason we don't all have jetpacks and personal helicopters.

    On the upside, a lot of these fantastic visions do come to some level of fruition. When car companies make concept cars, some features may trickle down into production cars.

    As a public, I don't think we typically want to change how we live drastically. Few people want to embrace something like the Kyoto accord to reduce pollution because it hits them in the wallet.

    A lot of Dot.Bombs went this way because they were counting on investors and the public to embrace new technology because it was COOL and drastically would change how we manage our lives. Didn't work.

    If you think about it, most 1950s guesses about the future centered around dreams of mechanical engineering. Jet-packs, personal helicopters, etc.

    It turns out that complex mechanical stuff is harder to design and mass-manufacture than formerly believed. So today's reality in terms of mechanically oriented consumer items in no way measures up to 1950s hopes.

    At the same time, while 1950s soothsayers dreamt too big in regard to mechanical developments, they dreamt way too small in regard to communications developments. And, if given the choice, I'd much rather have email and web broadband access for $45/month than my own personal $20,000 helicopter. I suppose I'd rather fly to Mars than own a cell phone, but the technology behind a cell phone is in many ways more miraculous than anything that's been developed for affordable space flight.

    The future we live in is in some respects a disappointment compared to 1950s hopes, but in other respects it's infinitely cooler than anyone could have dreamed of.

    The reason these exciting and liberating developments have not arrived is because of the political and business models that have driven (or hindered) progress since about the 1950s. a) Businesses, including Sony and Microsoft, create products that are intentionally flawed and never feature perfect, therefore, forcing consumer into a lifetime of upgrades. In addition, they keep changing standards, which again, defers utopia. Far worse, other types of business (I have met execs from these firms) exploit the consumer, in particular the poor, and they end up purchasing products that rather than liberating them, cause them strife. The cure for such strife is then purchased from another company that just happens to be part owned by company responsible for said strife. (Example, Longs Drugs sells very unhealthy processed foods sold to the naive underclass, which cause illnesses that are cured by the medicines for sale on the other side of the isle.) b) Politicians are paid by corporations to restrict the development of any product that will damage the growth potential of said corporation. For example, in the 1950s, the US auto giants purchased the public transport companies in major US cities. But rather than use imagination and efficiency to create the promised utopia, they ran them into the ground so they could sell people cars instead. Well, look what it did to LA and London. Fortunately, the latter is now cleaner and more pleasant to live in thanks the recent and somewhat utopian congestion charge imposed by our visionary Mayor. More buses, newer buses, better buses! and reduced fairs have made the city so much nicer just in a few weeks thanks to a massive reduction in traffic and greater reliance on public transport.

    The sooner corporate greed and lack of compassionate visionary leadership go the way of the steam engine, the better we all will be. And folks, that time will come soon, as world opinion on the oil war is proving. The Hydrogen Economy is the future. And flying cars will arrive soon too. Only one problem to solve on that, an affordable, effficient, safe and quiet engine. But humanking will do it, we always do!

    It is interesting to look at past predictions of the future because they can tell us how difficult it is for us to truly think creatively. In most cases, we are so limited by out prejudices and assumptions, that we can't really predict anything past next Thursday. I really believe the value of these predictions is to remind us of who we were, rather than tell us who we are going to be. For instance in many mid 20th century science fiction, the 'simple' tasks of cooking and cleaning were handled by robots, but the 'complex' tasks of navigation still had to be done.

    OTOH, exhibits like this speak to the great optimism of human nature. Though it took Europe five hundred years from the time of Marco Polo to the time that they colonized a new continent, we were in the mid 20th century certain that we could conquer the solar system in fifty years. The same holds true for helicopters, jet packs, and everything else.

    Has anyone noticed that "Tomorrowland" in Disneyland is starting to looking like, well, yesterday? Many of the attractions are either outdated (Astro Orbitor), closed down (RocketRods), or just altogether too plain (Innoventions). Space Mountain is great for thrill seekers and my personal favorite, but wasn't Tommorrowland supposed to show off the crazy inventions of the future?

    Yesterland [yesterland.com] is a good place to see all the old, semi-forgotten attractions that seemed ahead of its time. Anyone remember those hovercraft bumper cars? [yesterland.com].

    Plus, Disney's got plenty of room to play around with right now. The old CircleVision attraction, the building right across from Star Tours, has been closed for a while and just sits there, probably only being used for storage. And whatever happened to those submarines in the lake?

    Disney, take heed! Don't just devote an attraction to the newest technologies. The industry moves too fast these days to keep up. Instead, why not show mock-ups of these sorts of retro-tractions? I can think of a ton of cool interactive exhibits they could produce (think Jetsons), even with their cost-cutting mantra of recent. Now if only they'd bring back those RocketRods!

    The flying car went the way that civil aviation in general is heading: sued out of existence, or prevented from moving forward due to the prospect of being sued out of existence.

    Progress is dangerous. If I make a product that will kill one user in a million, and everyone in America buys one, I'll face two hundred and eighty wrongful death suits, class action suits, branding as a mass murderer, and ghod help me if one of those failures happens during sweeps week.

    Flying is fairly simple, but the consequences of error are rather specatular.

    Cars were invented before lawsuits were so widespread; this is part of the reason Ford isn't bankrupt from all the innocent bystanders crossing the street in front of their potentially lethal products.

    But the tort system in America is biased towards the right to be stupid and my obligation to accomodate your stupidity regardless of what you're doing with my product. So no, I'm sure as hell not going to build you a flying car just so you can sue me when you fuck up.

    Looking through the Syndicated section I see a total lack of concern for safety. Mailmen with rocket pack but no helmets or flight suits. Space hospitals with no failsafe systems. etc... Amazing.

      In a lot of cases, what we *thought* was aerodynamic turned out to not be so once we had the computer capability to model airflow more accurately, under more realistic conditions.

      What works in a windtunnel doesnt always work on the road where there may be a tailwind, side winds, etc.

      Cars travel so slowly most of the time, that aerodynamics simply isn't important. What is important, is to reduce turbulance noise - wind hiss. The importance of reduced drag on cars is mostly advertizing hype. As a case in point: Look at the bottom side of a sleek looking car. The manufacturers clearly are only interested in 'visible' aerodynamics and don't care about the other half that is not visible. So it is just about looks, not drag. Those big spoilers on the back of Hondas are not to reduce drag. They increase drag. If anything, their main purpose is to provide a handlebar to push them with.

        Rule of thumb: if a 1-litre car is going greater than 30mph or so , aerodynamics really matters. There's a v-squared term in the maths.

        Spoilers are to increase turbulence at the rear of the car, thereby shifting flow separation further back, and actually reducing the pressure drag. If you don't know what pressure drag as opposed to frictional drag is, then this explanation will make very little sense to you...

        Properly designed spoilers really do work (but only at the particular designed speed ranges). (note: large third-party spoilers on the back of hondas don't work :-) ). BTW, Hondas really can go very fast. Most of the "rice-boy" stuff in america is american car industry propaganda - you'll find, if you go to europe or asia, EVERYONE LAUGHS AT STUPID GAS-GUZZLING AMERICAN CARS, and prefers well-designed, efficient cars like hondas.

        A rough undersurface of the car is also actually desirable (again, to INCREASE turbulence, though this time it increases drag) - the more turbulence, the less ground-effect lift will be generated, so you car doesn't take-off!

        Foils (often mistaken for spoilers) on F1 cars and some rally cars, are upside wings, designed to increase downforce (at the expense of greater drag), thus increasing traction at the wheel.

        Note: IAAFD - I Am A Fluid Dynamicist. Almost all the fluid stuff taught in secondary school is at best lies-to-children, downright wrong most of the time.

          It would seem that a rough underside is desirable *if* you have a downforce problem. This is not something your average commuter is worried about-- nobody lifts off, even at 80mph, on their way to work.

          However, a smooth underside would seem to be beneficial for air resistance and thus to fuel economy. Honda's engineers and fluid dynamicists and whatnot agree, as their most efficient car (the Honda Insight) has a smooth underside [openfrontier.com] to reduce drag.

          In particular, note where the article states "Another important aerodynamic detail that greatly contributes to the Insight body's low coefficient of drag is the careful management of underbody airflow." And the numbers they quote for power required to push the car through the air are equally revealing-- "In comparison, the Honda Civic Hatchback, with roughly the same 1.9 square-meter frontal area as the Insight, has a Cd of 0.36, and needs around 32 percent more power to operate at the same speed as the Insight. "

          So there you have it. Without the smooth underside, rear-wheel covers, and a tapered back-end-- you need 32% more power to push a car with roughly the same frontal area. I'm not sure I'd say "A rough undersurface of the car is actually desirable" without qualifying it by adding "for a race car, but not for a normal automobile."

    • Well, you're getting a glimpse of it today. After all, this story will probably be re-posted on ./'s front page again tomorrow. The only reason we can't say for sure is that ./ is governed by the reverse heisenberg uncertainty principle - ie: you'll never know either the (editor's) position or speed, since they're both indeterministic quantum states :-)
