No one is saying learn to hack is the solution to the issue. Regardless of doing it alone, or finding a team, it'll be an invaluable tool. It'll help him play a more significant role if a team was formed.

Stop refuting everyone's opinion.

It's not part of the solution here. It's just a good investment if you are running a tech start-up.

For example, if there was another partner here that knew how to hack, but wasn't a nurse, I'd say: Learn as much as possible about health care - it's your industry.

Either learn to hack, or find others who are passionate about the idea who can hack. Rather than people who are passionate about a salary. But doing both is a good idea IMHO.

Would definitely help them manage developers in the future. The best manager I ever had couldn't write a line though.

You can be a sole founder you know. Works quite well :)
