Let’s assume for a moment that Jason Knight is wrong (most probably he’s not) and this… service can create an awesome app for you. Do you know what this awesome app will still miss?
Business logic.
No matter how awesome such a tool might be it won’t be able to model your business logic for you. Thus, the generated awesome app is nothing but a framework, of which we already have enough out there. Or something we call a boilerplate; of which we also have tons out there.
I wouldn’t say i don’t use such frameworks or boilerplate generators every now and then; it takes off a huge load of typing from my fingers, but there’s a reason no truly big apps use them. At the end you will strip them down so much it won’t be a framework anymore, but a specialised piece of code written for your own business logic, by your own programmers.
