Key question is WHY did you take up this job in the first place? Do you really believe in the mission of this company or just the CTO title and a lucrative pay attracted you here. If you truly believe in the mission of the company, you're doing the right thing by taking all crap and making progress towards end goals. You are probably not coding because your time is better spent doing what you're doing now. Will you make more difference to the world if you went back to the coding role?
