Speaking as a nearly lifelong developer of one kind or another, with ASD and ADHD... there's a big ol' overlap. I'm not talking "the venn diagram is a circle" level overlap, but it is significant. Lots of people with these traits have personality quirks, differences in socioemotional processing from the "typical" stuff, experiences in early life, and other things, that can cause some pretty intense rabbit holing/spiraling when things get overwhelming.

To be clear though, this guy is obviously just a major dipshit. Nobody deserves being lumped in with that.
