The main problem is that as a software developer most of us worked at software product companies all our life and I noticed that often we know more about software product design and product strategy than some of the 'idea people'. People who never worked as developer OR product manager OR designer and have no knowledge in any of these fields and have no money to afford a payed developer are rarely the good co-founders. I absolutely agree with the OP that most of these people need simple CRUD apps, and the reason they need a 'cofounder' is that they need a mediocre programmer but have no money to pay them. I don't even like the term 'technical' vs. 'non-technical'. Ideally a smart person in the tech business should be somewhat 'technical'. If absolutely and categorically non-technical then they should be really-really exceptionally good in something that is absolutely needed for the business. (For example having a large following.)
