I'm too young to have formally "worked" 30 years ago. I did create a lot of code for fun, and some of that saw practical use for a business within the family.
Therefore, can't say much about the work part. It may be result of having grown up, but the most significant change I feel is perspective. Back then there was no tomorrow. No worries (or hopes, or plans) that anything created would need to maintained, or obsoleted/replaced by anything in future. Everything was right here, right now. Today, anything comes with an expected life-cycle, at least implicitly. Constant worries that the next minir OS, browser, language, ... update is going to break something. Back than, if it ran on MsDos 3, it woukd run on 6. And most likely in a command window of windows, and OS/2, too.
