        I think I'd be a late adopter after all the kinks have been worked out of the wetware/software interface. You know, the terrible seizures, adware/spyware being uploaded into your ceriberal cortex so your driving along and suddenly you get a big popup right in your field of vision and you crash your car, etc.
        • Well, one of the largest problems is the granularity of the sensors. It only has a 70% effectiveness because the sensors are too big to read all the neural activity. So we need smaller sensors.

        • simply don't allow any interfacing that could upload information to your brain. keep the signals going in one direction while allowing a "buffer check" to keep information from overflowing i.e. Your arm can only exert so much pressure as defined by the "control chip" so it doesn't ruin itself. This could be applied to the brain sending info to the computer, just design the software so it reads what's going on, and by the next signal sent, it can determine that any previous signal was actually interpreted by

          Working out the kinks is a critical step indeed. I interned at a bioengineering lab this summer, and a huge problem was just keeping channels active. The brain sloshes around inside the skull quite a bit, and to have a stiff electrode intrude on this can be problematic to say the least (if a jet pilot with an implant were to pull a few Gs I imagine some sort of self lobotomy).

          Next are immune reactions to foreign objects in the body. Coatings over the electrodes can help, but are not a guarantee.

          Finally, these electrode arrays are pretty large. Technology can improve this, but imagine invasive brain surgery every time you need to upgrade, or being stuck with the 1st generation mind-link ipod for life.

          I'm waiting for nanomachines to solve many of these problems. When (and if) I make it to grad school perhaps they'll have it set for me... or maybe I'll volunteer as I'm never going to fly a jet.

        There are always some wrinkles to be worked out of the first generation of any new technology.

        Getting the latest generation of graphics card and finding that it somehow interferes with playback of my old .viv movies is a nuisance.

        Getting the latest generation of cyberware and finding that it causes epileptic seizures in combination with the interference with my cordless phone? Rather more than a nuisance.

        All things considered, I'll let the parapelegics handle the alpha testing for all this stuff, thank you very much.

            I keep thinking that a 'human bus connector' would be a good idea, once you've identified the areas of the brain most conducive to electrode implantation for control purposes, you create a standard connector and tolerances for the controls. Identify motion axes that can be trained. Create a computer that hooks into the bus connector (mounted in the most logical place, perhaps behind the neck?) and allows the user to train using the motion axes in a therapy environment, then move them up to the vehicle that can provide mobility, a grasping hand and communications.

            The advantages of this would be that as new hardware is invented, the brain electrodes wouldn't need to be re-implanted and the new hardware could simply take advantage of the existing control interface.

            It's been a dream to regrow spinal cords. This provides a technological end run that while not 100% desirable, gives them a far more mobile and productive existence than would otherwise be possible.

    One possible reason why such advances seem to take longer than for the pacific tectonic plate to move a mile is the hemlock cup with its swill of politics, corporate greed, litigation and religion. Between them, they throw up enough obstacles in the path of medical advancement - sometimes justifiable on ethical grounds - but mostly to advance to their own selfish power plays.

    If you consider that effectively all human input into a computer is brain-controlled. It's just a matter of what transmission method is being used. In normal cases, such as most of us here, the transmission medium is (simplified): Brain to fingers to keyboard to computer.

    The big thing about this is that now they are working to take out the fingers and keyboard part, and make it "Brain to Computer."

    Honestly, I see a few frightening issues, though. For example, I can walk up to my computer on a dry day, sit down, grab the mouse, and send a static shock through the USB port, effectively freezing the USB capability. Now, what happens if somebody is using this wonderful new technology, and gets a static shock straight to the brain? Or, for even more fun, if there is no isolation circuit in the input system, what happens if the power supply to the computer blows and applies a comfortable DC voltage directly to your brain?

    The entire "In" part is what bugs me. "In his skull", "In his brain"... It makes it seem more exciting, but honestly, IMHO it opens up so many more possible problems. Just the fact that you need to get brain surgery to just START to use this thing is enough as it is. If it were non-invasive, I'd be a lot more impressed.
