"Let's get non-musicians making music! We'll just give them a nice MIDI keyboard instead of that hard-to-use violin"
Sure, this will skip over some tricky bits of getting started with programming, just as a MIDI keyboard can make it easier to make violin sounds without having to learn all that pesky fingering.
However, as with playing the violin, those bits aren't really the hard part to learn; the easiest to use keyboard in the world won't make you a composer and flow based programming is not going to make you a programmer.
MIDI tools enabled more people to make new kinds of music.
Not everybody will be a programmer, but hopefully a slightly larger percentage of the population will be able to discover the power of algorithmic thinking, and hopefully they will work on some interesting problems.
