Over the years I have come to the conclusion that the T in CTO could literally be anything. It's just a coincidence that it happens to lead the technical organization. It could literally be anyone with some master degree in management or similar. The bigger the company, the more it's just an administrative job. Most of their work is delegated to some VP that, if you're lucky, will have some technical background.
The CTO is just a guy keeping the balance sheet in order and nodding at what Sales/CFO/CRO says.
6 months as our CTO. It has only one goal: reduce costs. Since he came, he's obsession was that all IT teams under his coordination are "too fat". The bad part is the hierarchy trusts him (for a reason). It's Balkans here... anything goes.
