...Google Translate? Photos search? Gmail autocomplete? YouTube recs? Heck, Waymo?

I can't think of any other company that has produced more ML that I actually use daily. (Well, I don't use Waymo... yet.)

So I really don't know what you're talking about. And presumably they're not jumping into public versions of chat and image synthesis like ChatGPT and Stable Diffusion because they're busy figuring out how to apply them in ways that will actually make boatloads of money.

Oh, and pretty sure Search uses tons of ML as well... they just don't go around talking about it because they don't really need to.
