Since employment is apparently the highest achievement a person can aspire to, this post and emacs users in general, must be of such lesser value I guess? /s
The implications behind gene propagation being one of the highest achievements a person can aspire to are quite unfortunate to consider.
Regardless, I don't think anyone is going to, say, avoid a specific doctor because said doctor is fond of Emacs. Same for a plumber, a baker, an electrician, a lawyer, et cetera. As a matter of fact, I have a hard time thinking of any profession where a fondness for Emacs may be considered a bad thing. Perhaps a software developer may have a harder time finding gainful employment if potential employers find out about the preference for Emacs, though that would likely only be an issue among a limited and specific set of potential employers.
Never in my 20 years of programming, data engineering, engineering management of games, search engines, dating apps and machine learning systems I had a problem of people not wanting to hire me because I prefered Emacs (and linux).
The opposite is also true. I have never heard anyone climbing the ladder specifically because they are "so fucking good" with [insert whatever IDE/editor]
Dude is saying nonsense. "Emacs users are unemployable" sounds like "Tesla drivers unregisterable" - what an imbecilic, utter bullshit that has zero sense to say. Ever.
