They've stopped technological progress. I tell you since AI started taking over, my experience is that nearly all forward progress (in software at least) has come to a halt. We've been standing in place, maybe sliding backwards a bit.
Here's the thing about AI: intelligence isn't a new thing, and it isn't a tool. The Amish can tell you that having a brain doesn't meant that you don't need a plow. In some ways they're much smarter than the AI crowd, all of who loudly keep insisting that brains will make plows and tractors and combine harvesters obsolete. You're so convinced that intelligence is the ultimate replacement for tools that you've stopped climbing the tech tree of tools...
It's like the tech industry itself no longer believes in technology.
I'm not even talking about holographic game consoles or FTL travel. Why can't we finally have a good container orchestrator that's not kubernetes for example?
