The app-building app that ultimately wins is going to be the one that lets you build any app, not just an app that serves a particular niche or business process. We have those already. They're called IDEs. It turns out there's only so much complexity you can hide if you need to describe what you want to do unambiguously enough to be executed by a machine. Something like Visual Basic is probably as far as you can bury complexity while still being widely useful. Go much further and you start to drastically constrain the range of apps that can be built with your app-building-app. SQL is just the lowest-common-denominator notation for accessing and manipulating data by performing operations that can be represented by relational algebra and relational calculus. Fixating on the language itself misses the point that there is a theoretical underpinning to why data is handled this was in many practical applications.
