it won't.
"ai" (llm) is a fad same as nft's.
While nobody really cares about "ai" the companies all spending to make it better will give us in time better digital assistants for those who want em.
"ai" won't ever be profitable as its too "dumb" to pay for (it "might" have a spot in making game npc's more unique but very few would ever pay for that stuff except maybe to experience it once) . Big tech will learn this in time but doesnt change fact its beneficial for those who might wanna use it in future.
also "ai" might backfire on some stuff as it would possibly enable cracking of paid content in film, game, pc application, etc. (new tech has always had good and bad outcomes and not really anything can do about it) since its been proven llm can be tricked into doing "bad stuff" even if theres rules that shouldnt allow it.
Let the big firms waste their $ and just eat popcorn as you watch it unfold.
