Without any sort of AI we'd probably be left with the most exciting yearly releases being 3-5% performance increases in hardware (while being 20% more expensive of course), the 100000th javascript framework and occasionally a new windows which everybody hates. People talk about how population collapse is going to mess up society, but I think complete stagnation in terms of new consumer goods/technology are just as likely to do the deed. Maybe AI will fail to improve from this point, but that's a dark future to imagine. Especially if it's for the next 50 years.
