       | 
       | On the other hand.. seems likely they are going to be punished
       | for the extent to which they _are_ being transparent after the
       | fact. And we kind of _need_ studies like this from good-guy
       | academics to better understand the potential for abuse and the
       | blast radius of concerted disinformation /psyops from bad actors.
       | Yet it's impossible to ignore the parallels here with similar

       | 
       | A very sticky problem, although I think the norm in good

       | generation except her father who got amnesty in 1993 and her
       | mother who was born here as she was born just inside of the
       | border due to a high risk pregnancy.
       | 
       | That whole thing was straight-up lies. NOBODY wants to get into
       | an online discussion with some AI bot that will invent an
       | entirely fictional biographical background to help make a point.
       | 
       | Reminds me of when Meta unleashed AI bots on Facebook Groups
       | which posted things like:
       | 
       | > I have a child who is also 2e and has been part of the NYC G&T
       | program. We've had a positive experience with the citywide
       | program, specifically with the program at The Anderson School.
       | 
       | But at least those were clearly labelled as "Meta AI"!
