Interesting topic. There is nothing you can lose by starting a friendly "debate".

There are three likely scenarios:

1. You are wrong, CTO is correct, and you learn something valuable.

2. You are correct, the CTO is wrong, and he gains respect for your initiative and skillz

3. You are correct, the CTO is wrong, and he loses respect for you.

First two are obviously good, 3rd one is a good sign you probably won't or shouldn't stay long there.
