I my experience, those who don't care about performance almost always happen to be bad developers. Interviewed with plenty of those. I've worked with machines so underpowered you can notice execution time difference between minified and non-minified code. And where CSS animations are considerably slower than GIFs. Oh yeah. Right now I am with people who are pretty good at architecture but kind of suck at the pieces that power their designs. It's an ego problem. Big one at that
