Ah, the answer is incredibly simple: my aunt speaks fluent German! She moved to Austria as a young woman and picked up the language, and picked up a husband. :) She speaks Korean, of course, so that's how we all are able to communicate with her. Recently we were at a family gathering, and one of my extended relations is married to a German fellow (who speaks both German and English fluently), and it was utterly cool seeing my aunt and him chat away in German (and sing "99 Red Balloons (Luftballons)," the popular 80s tune by the German singer Nena, in their native German)!

I feel this in my engineering work. My software goes into cars that are mostly bought by rich people. Not very satisfying. I'm somewhat lucky my work goes into real products rather than shelved research projects. But I get my kicks out of helping friends and family with IT tasks. Set up a pi hole for someone. Give them an openwrt router with a wireguard VPN to my jellyfin server. Set up a cheap thinkpad with Debian. It's basic but it makes a visible difference.

I suggest you run this by an actual doctor.

I had the same kind of childhood with the VIC-20 and C=64 (and TI-99/4a in school as well). And having launched my career in I.T. I started as a Network Operator and then quickly promoted to systems administration, with SunOS 4.1.x mostly.

And I had purchased a beloved briefcase which I dutifully took to work each day, but my job wasn't really working with paper, much less anything that I needed to bring home with me.

And through those early years I really did fret about this: I produced nothing tangible at work. My work wasn't classified or secret, but there was nothing relatable I could really discuss about my work! What could I show people to prove I was a productive worker? How could I prove my worth, such as later on a résumé to a future employer? There was really just nothing.

And it went on like this for decades. I am sure that I, like many, struggled mightily with this intangible nature. Even my father, as a scientist, at least he brought home the Geiger counter, the film badges, the pager and the gadgets.

Find an IT-related problem facing the whole world right now and fix it.

For example phone enshittification. Make your own phone that isn't shit.

How do you figure? Commodore had strong sales through the late 80s, and the C64 wasn't discontinued until 1994.

My family's C64 was the first computer I ever used, and I am barely in my mid 40s. And although my family later purchased an IBM PC clone around '89 or '90, that just meant the C64 moved into my older brother's room, where we used it even more.
