all you've done now is change the question from 'what kind of developer do you want to find' to 'what kind of co-founder do you want to find'.

Or would you tell someone to trust their gut and blindly pickup a 'technical' cofounder?

No, I would tell them to talk to as many technical people as possible, and look for one who proves able to:

a) understand their vision b) improve on their vision c) get some respect from other technical people

With a) being the crucial step, and if they can't get past that there might be a problem with their vision.
