I was able to become literate in code, but I don't think become a "10x engineer" that a proper technical co-founder should be is feasible for me. I can create a simple, but decent, front-end; and I can understand discussions of back-end code. That is sufficient to me I guess.
But working on a "hot startup" in Brazil won't happen and "sell my startup", well, I am trying to build one. I will never cover all my bases, but you are right, maybe YC isn't for me. That's not that bad either, I can do without. But I can't deny that I want it very badly.
