Are technical co-founders supposed to build the entire app!? (As a technical founder)

I came across a post yesterday about someone being fed up with not being able to find a technical founder to build their app. As someone with 15 years experience as an engineer and in startups I think this is mind blowing. It’s a little bit like someone saying I started a company that goes to the moon and for 50% of the company, I will let you build the rocket! A technical founder who has to build the app undoubtedly would spend months working nights and weekends getting a polished app and leveraging skills it took them a decade to acquire. Any asshole can demand types of authentication, crud functionality, ChatGPT integrations, etc. It takes so much work to acquire the skills to build end to end functionality, scalability, reliability, and the ability to execute that this relationship is drastically unfair. So unless the non-technical co-founder is bringing dozens of customers with cash, I say skip!!! Software development is a team sport. And unless everyone is technical to some level, the relationship won’t work.
