I studied CS so I used to know quite a few. The ones I hung out with though were only incels in the literal sense. They couldn't get any because they were way too shy to flirt/ask women out, too socially awkward, put almost 0 effort into their looks, etc. but they were very nice people and respected women
I actually know quite a few incels (in the more common sense) now in my workplace/mutual friends (all tech bros, ofc) but I don't talk to them + they actually all have GFs/wives because they're rich/their partners are just as offputting as them
