Really, I don't want to discourage anyone from learning, but suggesting that you can learn enough to launch a startup is kind of like deciding that you can do web design because you've used Word. Some people will be able to pick it up in a month, and some will never learn to write decent code.
There's a reason people pay me to sit and stab buttons on a keyboard.
In six months you can easily pick up the basic ideas need to converse with someone about technical issues, and at least understand what the other person needs. Maybe you'll even learn enough to help out and create the demo, or something.
a.) Someone who says they have a 'killer' startup idea but no technical ability to execute it.
b.) Someone who has an idea and has already executed a working prototype of that idea for you to check out.
If so I would take the one that can handle that side better.
The first iteration of a startup will almost always be wrong and you'll have to throw most of it away. So it doesn't matter so much whether its the best code in the world or not. The important thing is that you learn from your first iteration. If you don't have a tech background and hand off the first implementation to a superstar, it's very possible that you won't learn anything. If you do it yourself, you will learn a lot one way or another.
Also, it helps in many ways to be able to demonstrate that you are not an idiot.
Being able to call BS from your developers or a perspective co-founder doesn't require you to be a programming god.
