It seems like the problem with many of these tech companies (and many modern companies in general) is that they've scaled faster than they have the ability to operate properly.

    "How can we possibly moderate properly without AI?"

is really just another way of saying

    "We don't want to pay the money it's going to cost to moderate effectively and we're going to cross our fingers that we can solve problems caused by technology with more technology."

That failure to operate is causing harm but the kind of harm it causes is hard for the public or politicians to understand, so it goes on unaddressed.
