I updated my comment a bit with other stuff, so you can check that out.

Out of the schools you mentioned only berkely has an EECS program (that I know of). I think you might of used just CS if it was another school. The roblox games also kind of give me berkely vibes. You also used they/them pronouns to describe your child, though that was not a good or conscience reason, it might of slightly affected my biases in retrospect.

I also know gaming addicts that go to berkeley (although I know a lot of people that go to berkeley in general).

Other than the first reason, I can’t really explain it, which is why it was a complete guess.
