This is very interesting could you please describe your experience in more detail? What was the turning point that made you want to share this idea here?
Recently, a colleague of mine was presenting their work. Another colleague with CSPD (comp. sci. personality disorder) interrupted the presentation to say "this all seems very obvious." The remark was self-aggrandizing and completely dismissive of my colleague's hard work.
Witnessing this made me realize just how toxic our community can be to one another.
Ok, but was it wrong?
Put your friend's precious fee-fees aside, and ask yourself the important question: was it wrong?
If it wasn't, then it sounds like the problem was with your friend, wasting everyone's time with a pedestrian analysis that benefited nothing except for their own ego, so they can be heard, so they can climb that all-important neurotypical status ladder, so they can put another insignificant bullet point on their C.V.
