This isn't AI damaging anything. This is corporations damaging things. Same as it ever was. No need for scifi non-human persons when legal corporate persons exist. They latch on to whatever big new thing in tech that people don't understand which comes along and brand themselves with it and cause damage trying to make money; even if they mostly fail at it. And for most actual humans they only ever see or interact with the scammy corporation versions of $techthing and so come to believe $techthing = corporate behavior.

And as for denying service and preventing human people from visiting websites: cloudflare does more of that damage in a single day than all these "AI" associated corporations and their crappy crawlers have in years.
