I'll just stick with Neovim until something better comes around. Which probably won't happen until after the "AI" bubble bursts.
I guess it's always possible to return to Vim if Neovim starts showing signs of being steered by its sponsors.
A whole lot of "AI" features today are in that "solution looking for a problem" category. There's a lot of "AI" in places where it really makes no sense at all. Companies and projects are afraid of missing out on what they think could be the Next Big Thing, instead of just trying to make the best software they can.
When the AI bubble bursts, it could end up like Internet features: software gets them when it genuinely makes sense, but they won't be crammed into software which has no need for it. Or it could end up like cryptocurrency: it pretty much just disappears as people realize that they don't really have any use other than to speculate on its value and to buy drugs.
Personally, my bet is that they'll end up more like cryptocurrencies. After all, "AI" doesn't just have to be a useful feature to be worth it. It has a real cost. Companies like Microsoft and Apple and Google, as well as the venture capitalists and investment funds behind the likes of Anthropic, are currently sinking VAST amounts of capital into giving "AI" away for free or heavily subsidized. At some point, it'll need to become profitable, and I don't think many people will find that the value outweighs the real, non-subsidized costs.
But we'll see.
