I wonder if there’s a parallel universe where the labs instead went to the other extreme and require intelligence tests to onboard to their platforms.

And the outcry is, not inappropriately, about how many are being denied access to the latest technologies. The policy could effectively be construed as racist, even.

Anyway the middle ground there is pretty obvious. (Though I’m not sure how I’d design it just right, so e.g. folks without access to traditional/expensive mental healthcare might still be able to see some small benefit if it’s determined to be safe, just like maybe it could be safe for a well-adjusted individual to complain to it about their day for a couple minutes before moving on to real things. Sure I suppose it’s inherently unsafe but a proportion of the population should be making that decision for themselves.)

I agree with a lot of the things you said about the problems with AI but not that this is one of them.

If it wasn't this it would have been something else. People with mental health issues can get fixated on things and spiral until they act out. This has been a thing for as long as there have been mental health issues. It's not a failing of AI, it's a failing of society for not having sufficient mental health support to catch people like this before they go off the deep end. They shouldn't have to turn to AI in the first place.
