I do have devices that can read tape written 20 years ago. 8-track was from the 60's and 70's by the way, making it a bit more than 20 years.
First CDs came out in early 1980's. That's 30 years and the drives are still backwards compatible -- I can still put in my old Pink Floyd CD into my Blue-ray drive and the computer will play it. There is no reason to believe that won't continue for another 10 years or so as music is still being released on CD in commercial quantities. Despite the hype optical disks are far from dead.
Archival quality optical disks have a good chance of continued support because there is a substantial effort being put into them in the background by people like the National Archive, Library of Congress, and others looking for means to maintain long term records storage. It's not guaranteed that they will be around in 100 years. Maintaining any system that long is difficult, even simple paper. It's got as good a shot as any though.

There is an increasingly large number of devices (just about every lower power device of the last 5-7 years) which will play h.264 and not divx. Since the era of the iPod 5th gen ("iPod Video") the trend has been for h.264 hardware decoders paired to relatively weak CPUs.
disingenuous sarcasm never got anyone anywhere, so good luck with that.
As if suggesting DivX wasn't sarcasm...
Yes, I can come up with a thousand free market answers. And yes, that pretty much answers your question.
Would you buy a vehicle from any company whatsoever if you knew that parts were difficult to acquire? A manufacturer can play a game with parts availability only if they don't plan to stay in business.
Maybe we should go back to renting our phones from ATT as well.

An industrial site or process is generally the result of experimentation carried out in a lab. That means shit in the lab sometimes goes wrong.
They're making a comparison between university labs and commercial labs.
