I miss how simple programs were in the 80s and 90s. I mean, they were a lot of work because there were no powerful libraries and you had to do almost everything from scratch. And then wait 30 minutes for the compiler each time you did a build. And it was way too easy to lose work before there were usable version-control systems (and even with the early ones, like CVS, it was easy to shoot yourself in the foot).

Stuff that was a major challenge back then, like rendering a polygon or keeping the state of an HTML form, is trivial to do today. I wish I would be paid to write early 90s programs with today's tools :)
