I've been a professional developer for more than 10 years and I have similar observation. Most of developers don't use touch typing. And it doesn't seem to affect their efficiency at all. Developers usually don't need to produce large amount of code (unless you are Go developer ;) ). They use auto-completion, copy-paste and usually need to do a short edits and not 20 lines of non-stop typing. So even though I use touch typing myself, I've never seen this as a big advantage making me somehow better than others. I see benefits only when I am in a long chat discussions.
