I don't know. IT is a bit different in that regard. As a doctor, even if the system is shit, you still help people directly. As an engineer, you build something tangible that can make people's lives easier. And so on. In IT, though, the impact often feels much more indirect. Most of the time you're optimizing processes or helping businesses become more efficient, rather than improving people's lives in a direct way. You're often several steps removed from the people who ultimately benefit from your work. I'm not saying that's a bad thing, it just doesn't feel very meaningful to me.
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.
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.
