In 50,000 years, humans will probably not even be on Earth anymore. Either we will have annihilated ourselves, or we will have migrated to other worlds. In 6,000 years we have gone from the dawn of history to a worldwide information network and space travel. In 9 times that time, we should be much further along!
What would those constellations look like from our new homes near other star systems?

I'm dissapointed, the anology with 6k years looks not bad enough for a lot of people to agree (well, we all want to think that way...)
Though OTOH "since the daughter of my buddy has made tremendous progress in language during the first few short years of her life, in a few decaddes she should be able to communicate in any semi-popular language" (for example) is a bit too obvious giveaway.

But that wasn't the premise, it was about "we probably won't even be here anymore" - and while, sure, the progress is nice...some fundamental things stay strangely similar (which might not be the case anymore quite soon, sure; or we might be nearing some another long-lasting equlibrium state, similar to the one of our civilisation from 50k years ago; whatever). We should spread to few other areas, among them possibly Oort cloud - which should also present some people with opportunities of hitching a ride on

OP might have meant "we probably won't even be here exclusively anymore". The sentiment that a 2 dimensional constellation of three dimensional stars is colloquial to a fixed star system is not heavily influenced by whether or not we continue to inhabit the original system.
For example, we have a complicated rock formation on the horizon from the house where I grew up called Smith Rocks. From the angle of my house, the entire formation looks like a rhino. It was quite nice as a kid to have this Rhino chillin

Meh, plenty of people have worried about nuclear annihilation in the past. It is pretty well understood that a complete nuclear offensive would if not extinguish the human race, at least ravage the human population and set back civilization a century or more, not to mention ruining the continuity of what we see as history. We would probably arise from the ashes, but I don't think we would arise as the same people we were when we fell.

The conclusion is: not very much. The little dipper will become sort of triangular instead of rectangular. The Big Dipper and Orion will be mostly unchanged as far as anyone cares (Orion's shield will warp, but the belt--which is the only thing most people look at--will remain identical), and the only other changes discussed are to incredibly ancillary constellations like Hydra.
OTOH, there's absolutely zero discussion of a few of the stars most people have heard of and care about or any of the widely recognizable constellations outside of the big/little dippers. Will Polaris still be the North Star, or will it be replaced? Cassiopeia's Chair has famously become more and more W shaped--what will it look like as time passes? Will the Southern Cross--the flag of Australia, New Zealand, and several other southern hemisphere countries--remain the same?

Yep. The north star changes identity fairly frequently--that's part of why I put that in there.
It just seems really odd for an article on this topic to omit discussions of many real changes in stars and constellations that people actually know about while dedicating time to a slight deformation of the Big Dipper (which at least is near the top of known constellations, but apparently isn't changing much) along with discourses on Hydra and one little star in Taurus drifting.

what bothers me even more, is that the now picture for the little dipper, isn't even remotely near how it looks outside my window.

Maybe part of the reason is that we hardly ever see the constellations with a perfectly dark sky, and with clean air. Even away from cities now the air will be somewhat more polluted, and satellites litter the sky, though these effects should be fairly minor.
Another more subtle factor is that people today have a lot more to occupy their minds. The latest catastrophe in Pakistan; football results from across the world; 24 hour news, all that stuff which fills our heads with dubious information. Ancient peopl

Betelgeuse is already old for its size class and will explode relatively soon compared to its age. At the current distance of Betelgeuse from the Earth, such a supernova explosion would be the brightest recorded; outshining the Moon in the night sky and becoming easily visible in broad daylight.

"From The Earth" is rather prosaic when you compare it to 3 dimensions. Look at any constellation from the side. The distances are usually much greater than the apparent angular separation as seen from Earth. It makes it quite obvious that 'constellation' is as synonymous with 'illusion' as it is with anything else. But from the side you can see that some groupings hold, such as the majority of Taurus. Most of it is an open cluster, so of course things won't change much in 50K years, the members are moving
