I'm a developer working with business and from my experience, the most helpful knowledge a founder can have is domain knowledge. I mean you have to understand the business because the developers don't know all the specifics of your field, but they can choose a tech solution based on all your needs.
It's good if founders have some technical people on their side to communicate effectively with a development team, but it's not necessary. If you want to start coding before developing a product, you must invest a lot of time in learning instead of doing business. I believe that everyone should do their own thing.
The value of any technology depends on how you use it. GPT is good for data analytics, so it will perfectly complement cases where it is needed, for example, recommendation systems, customer support, intelligent search, etc. I see the value of GPT specifically for a business and not for an individual, although for me it significantly speeds up the data collection.
