I know plenty of tech-adjacent people whose interests stop at Wired articles, but it's really impressive you've actually dived (doven?) into the command line and Emacs, even to the point of building stuff!
You'll definitely be great at software engineering, as the intuition to dive deep into the bowels of these archaic ways of using a computer seems to come naturally! (especially compared to my attorney friends, who basically just use the browser, Outlook, and Word, and probably think a "command line" is some sort of military jargon)
