>they make some todo app, then they post the same video with a new language completely forgetting they've done this already 6 times

I don't see how this is bad. Technology makes iterative, marginal improvements over time. Someone may make a video tomorrow claiming a great new frontend framework, even though they made that exact video about Nextjs, or React before that, or Angular, or JQuery, or PHP, or HTML.

If it weren't for the massive money being poured into AI, we'd be stuck with GPT-3 and Claude 2. Sure, they release some duds in the tooling department (although I think Skills are good, actually) but it's hardly worthy of this systemic rot diagnosis you've given.
