If someone opened a massive free school for training sculptors and enrolled 1000s of students no one would believe that they would end up with hundreds of Michelangelo's. They wouldn't get lots and lots of excellent sculptors. They'd be lucky to find a 1 or 2 really good ones out of every 1000 students. Then they'd find a few more fairly good ones and the rest would be mediocre to bad. Some would be able to create really elegant statues, some would be good at making blocks, bricks and tombstones and the vast majority would make gravel.
The only difference between this and the mass programming schools is that with sculpting most people could look at their rock based product and easily discern its quality. Not so for programming. That's why this industry is rife with gravel producing developers who try and pass their product off as statuary.
I think the public is being deluded about this.
