That has to be the silliest reason to hate AI I've seen yet, next to the "don't you know how many gallons of water are being used up!!!"
Replace "AI" in that sentence with any rapidly evolving tech: social networks, smart homes, digital governments, hell - even online shopping.
The versions of any of those things a child would've read 20 years ago won't have anywhere near the complexities and unexpected downsides all those things ended up having in real life.
20 years ago, AI to (kid) me was a real life C3PO, or an npc in an open-world game that existed in that world with their own motivation and story independent of what you did. Or the stereotypical humanoid robot with consciousness like in the film "A.I.". No kid could've imagined vibe coding, running sub-agents, diffusion models, AI zombies, and all this other stuff we have today. Everything you imagined as a child is still possible, and depending on what exactly you read, is already here.
Yeah the UX is different than what anyone 20 years ago would've predicted, but how does this mean the "hate" make sense? That's not even 0.1% of the reason the typical anti-AI people are against AI.
