I'm not convinced it's selection bias, but just that there is a huge range in skillsets now. In my personal network, I'd estimate that more than 50% of the designers I know are competent front end coders. (I've worked at a couple of large agencies, so I know quite a few designers.) It's very rare that meet a designer who doesn't know any code or who isn't at least trying to learn. Most job posts for designers that I see expect knowledge of HTML/CSS as a minimum, but often also Javascript & frameworks, or even Rails. I don't really know of many programmers who have even a basic understanding of design. Sometimes, they even lack appreciation for design. Maybe that's selection bias too. Just speaking of my personal experience here. Maybe we're all just pointing fingers at each other. It's obviously productive for everyone to gain basic competency in the opposite discipline.
