> I don't mean to come off as a jerk, but I guess I'm just going to say it; in the 25 years you've been a developer, have you not tried to make a game? Yes! But there are lots of kinds of games, and none of my attempts were in 3d or involved physics. Also I've learned that without real users beating down my door for a feature I will not ever finish a project, so I've given up on "fun" coding entirely and haven't written any kind of game whatsoever in probably 15+ years. It's a waste of time for me, as I will not finish it. I need a guaranteed smiling face at the end of the process, or there's no chance I'll get far. If I decided I really wanted to make a game these days, unless unusual physics were vital to it, I'd probably let an existing engine take care of all that for me—why would I code it from scratch, when the point is to have a finished game, not manually write as much of it as possible at the expense of making it take longer? > Some machine learning? Never had a reason. I'll learn it if I ever have one. My usual approach to anything a whole bunch of people are doing, but I'm not, is to assume that some of them must be idiots, and they're doing OK, so, since I'm an idiot, I'll pick it up just fine, too—if I ever need to. This approach has yet to fail me. I've yet to try to do something new that lots of other people are doing and found that no, in fact I'm too dumb to pick it up pretty fast. See above about needing someone who wants the output of my work, before I can reliably finish projects. There's no way I'm going to complete a "learning project" in machine learning, for its own sake, unless I'm just very interested in whatever's being learned—and I just don't really care that much about machine learning. I get the gist, so it's not some big mystery to me how it works, OK, that's neat. I'll dig deeper if I ever have even the slightest reason to. Just haven't yet. > Data science? Not done anything interesting, or "real" data science. Fixing up data, yes. Doing very simple math on it, sure. If I ever knew what any of these: "ANOVA, Chi Squared, Student T Tests" are I've long since forgotten. Certainly never used any.
