The vast majority of active musicians don't make any memorable original music whatsoever. Sure, we'll have lots of good performers always, that won't change, but what popular music needs is huge numbers of relatively unskilled 'musicians' taking a stab at songwriting. That happens because there's money in the game. Otherwise we'd just be left with a dull cottage industry.
You're arguing that the music industry will be worse for lack of people with no discernible talent or even interest in music becoming songwriters for pecuniary reward. Seriously?
Yes, absolutely. What discernible talent did John Lennon have when he got involved with the industry? There is no level of training or 'talent' that has ever reliably led to great songwriting. Nobody has a formula for great songs, it's not like programming where one a great hacker = always a great hacker, able to get the job done. It's all just shots in the dark. You can already see as the money falls out of hip hop that it's dying out and fewer young rappers are appearing.
