I have seen a LOT of YouTubers advertising them (some were sponsored by them).

I remember seeing that ad in death battle video's. 

I am already finding so many search results with some popular search engines use AI. At least with Bing you get a choice as it is obvious it is using it but only on the side so you still get normal results in the main search. Google seems to really be embedding it in especially in image searches that it is hard to find what you want now but instead are getting results AI created.

It seems like everyone is gearing up for this AI craze.  Nvidia already has a foothold in the door with its Tensor cores in the RTX series cards.  And they are just going to double down on that in the future.  AMD and Intel will also be following suit.  Microsoft has already announced that they will be having some limited baked in AI support with Windows 11.  And windows 12 is rumored to have full AI support.  Giving that your CPU makes a certain threshold of compute.   As is, even AMD's Ryzen 7000 series and Intel's 14th gen top consumer chips fall short of that mark.  So now everyone is pushing hard to get their next gen tech out the door so they can get ahead of the game.
