I don't mind learning, definitely. I got into this field because I'm passionate about software and I enjoy programming a lot. But while I have a full time job and a large-ish family to support, it's hard to fit "3 years of professional React.js experience" into my spare time to put on my resume, so that when nobody's hiring iOS developers anymore, I can still get a job. That's what I'm talking about. A lot of the skills are very transferrable, but I've already been turned down for a few jobs simply because I just don't have the in-production experience with the exact technology they're hiring for, even though I could pick it up pretty quickly.
