At this point, I just assume anyone who advocates for the use of AI is actually just an output from some AI. Given that "human-sounding speech" is the thing that AI is most easily able to produce, and how many different AIs are out there, and how beneficial an army of never-softening commenters can be for any specific pet cause you like, I can't think of why it wouldn't be statistically irresponsible to not assume that.

I've met enough real humans with completely self-important defenses of it that I know that they exist, so I'm willing to at least give them doubt. But the assumption is that they are AI and they need to prove being human. To assume otherwise is unreasonable.
