When I first saw your post, my reaction was: CTO after only 4 years of work experience? I've been coding for 30 years now, working for 20, and only in the last 5-6 years have I felt capable of playing that role.

Kudos that you've taken that decision - it's a good one. You can take the time to really broaden your horizons. At which point I very much expect that you'll go back, but as someone who earned the respect, not someone who needs to demand it.
