There is nothing stopping companies from offering AI oriented apis. If they no longer have to develop a frontend but just have a "here is our logo" etc endpoint, then... goodbye react! Goodbye FE developers! And at that point AI will probably be developing the very endpoints that it consumes.
For frontend - yeah, maybe. Or maybe the frontend becomes much more fancy. I‘ve built complex frontends that took a year or two but could imagine it all in weeks. I would also like to be able to build it in weeks.
Honestly it doesn't sound crazy to me.
