Ok, I'm all for worrying about the impact of AI in jobs but... Living advertisements are easy to replace, what a suprise.
People who make actual interesting and/or funny videos, those that require personal work and are a direct result of the creator's skills or interests, are not really at risk of this.
Wow, a bunch of assholes just getting paid for showing you free stuff they got, pretending to be relatable and your friend while evading their taxes in Dubai, may be out of business. And think of those parents who won't be able to exploit their kids by getting them free toys and exposing them to the whole world!
I don't think I will lose any sleep over this.
They've chosen series with huge amounts of existing content to imitate and got bad stuff from it. I am not too worried for people making more personal content.
Yeah, maybe some time in the future you'll get infinite serial AI content with basic entertainment value. I'd say half of Disney productions already got there without needing AI, just shotgun writing. And lots of people are already bored of it all and now only look for the good stuff.
