Nobody is going to pay for ChatGPT. They'll just use the ad-infested version, like they do everything else online. Well some people will pay, but not enough to justify the insane amounts of money being poured into it by investors.
It's still an advertisement, and the underlying marketplace is similar (pay for access to change behavior).
The best uses of AI will be surveillance, propaganda, cyberterrorism, and automated military tech.

I think it is more insidious than that. AI shapes how people think not just what they think.
