Stability, security, and power shouldn't be the ends themselves, though. They should be used for something.
A train is stable, secure, and powerful, but it lacks certain features that an airplane has, like being able to cross an ocean. Trains certainly continue to be used today, but our overall system of transportation would be retarded if there were no airplanes, despite them being possibly more dangerous.
I think a really powerful system would increasingly abstract away the mundane things, like debugging, so that our system of programming as a whole would become more efficient. I consider the fact that we still program by text to be kind of a technological failure/disappointment, kind of like our failure to travel to Mars.
