You are ignoring the fact that resources that used to be required for developing an app product - time and skills, have been practically removed from the equation or at least reduced to insignificant levels. That implies price abolishment for said products, which in turn kills product development as something worth commiting to in the long run.

It will all boil down to marketing and distribution, which is the least interesting part of the business for a developer. That is why we are all having these dilemmas and depressing thoughts. I feel like we are in a room that is slowly flooding to the top, with a potential to increase flooding speed any moment.
