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.
