I think they can. I think every frontier LLM company in this industry knows exactly how to make money with an LLM and furthermore it's almost bulletproof - they just don't want to say it.
LLMs are going to be the most devastatingly effective ad delivery mechanism that we've ever seen once they start flipping the switches. They're going to load the context up with all your demographic information and preferences and advertising susceptibilities and then tell it to subtly suggest to you all kinds of shit you need to buy.
It's going to be nearly subliminal and so slick that you're not even going to know you're being advertised to. It will be like your best friend gently convincing you over a period of months to buy a new EV, or that you need to refinance your mortgage, or that you should move to Atlanta.
They know exactly how to make money with these things, they just can't be the first ones to say it.
