If you think that you want to live in a world where your life is heavily influenced by machines that were trained on the idea that you don’t deserve to exist, then yes, “toxicity” isn’t a problem.
But you don’t think that. Even if you think you do.
But you don’t think that. Even if you think you do.
A "neutral" policy here is probably a still unsolved philosophy problem.
(It's just your brand of toxicity, so naturally, you don't think it's a problem.)
Trying to make rules for a machine to behave in a decidedly nontoxic way is a fool's errand, then.
You're also assuming that AI is going to be used to heavily influence people's lives, but there's a good chance that all it's good for is ripping off copyrighted material and generating clipart that's good enough for powerpoint presentations.
AI is probably going to change the world in the way that NFTs did. And self driving cars. And the Alexa.
