Question to CTOs - are you happy? When I see what particular CTO does day to day, assuming he/she was an engineer before - it seems quite boring. It seems they've sacrificed their engineering side in exchange for a bigger salary.
A more senior leader I very much respect - when I was about to make the transition - put it this way: "I was doing great as an engineer but had so much I needed to get done, so they helped me put together a team of 4, which was great, because I could accomplish almost twice as much; then it was 30 people and we had a whole product I was proud of. With 200 I know I'm changing the industry..."
You have to learn different skills - how to motivate people, how to see potential conflicts and roadblocks and use them constructively - but the technical skills you bring to the table can make your impact much stronger; and I think I get to learn new ones at a much faster pace at a compromise that I can't go as deep in more than a few spots compared to full-time engineering.
