I concur, after LeCun gave the warning to PhD students to steer clear of LLMs I heeded it and can say my career is better as a result: why compete/join a hype cycle if you can help solve foundational problems.
The difference between AGI and LLMs mainly is in the architecture, specifically that LLMs freeze the entire network, whereas AGI would leave some of it perpetually unfrozen so it can update as it goes.
You are right because it does feel like shit. I'm not experiencing it with AI, but I did experience it several times with technology already. Not a good feeling!
And OP is right because that's what you can actually do - moving on. The thing you like, in the form you liked it, is already gone forever. What you can do on a human level is to take this experience, grieve for what has been lost to you, and later find a way to move on. What I can say is that I always something that ignites that spark in me, no matter how many times I have felt that I have lost it.
That's not your home town tho, you have no right to say what people should or should not enjoy using. And from other people's view, you are just an old person complaining the past was better.
