After 15+ year building stuff for others I would totally like to have one app that earns money and I don’t get requirements from bunch of business people.
you'd end up getting requirements from users yourself, instead of business people
Yeah, but I'd hope that I can understand my users.
At least someone who knows the system and cares about it with ability to say no instead of promising BS to any stupid idea to inflate quarterly results and then leave to a different job.
