I'm almost 40 and have no issues with this yet. Colemak is my favorite non-QWERTY and feels smooth, but sadly, programming was designed with QWERTY in mind. The 30% comfort improvement wasn't really worth it and there's a speed drop because I've been on QWERTY since 5 years old. I also use my laptop in well, laptop mode half the time, so eventually I went back to QWERTY. But it's actually surprising on mobile how much easier a non-QWERTY keyboard is considering it's two thumbs and your thumbs are at the pinky areas most of the time.
