This really connects for me. I'm a library maintainer, and it's very satisfying to me to know that my team's work leads to visible, measurable improvements in the apps that our users make, even if it's not tangible objects; it's still a bit of a "text on a screen" outcome, but at least I get to write changelings and release notes that detail what we accomplished and why it made things better (usually). I also suspect this is why so many people I know in the industry (myself included) have hard-physical-object hobbies like baking, brewing, cycling, robotics... we need to fulfill a drive to create.
