Fields need a large base of participants to produce great ones. This is exactly why software has been so extraordinary over the past 30 years: an unusual concentration of gifted minds across the entire humankind committed themselves to it.
In my view, Bach, Rachmaninoff, Cole Porter equivalents today probably aren't writing symphonies. They've decided to write code for a living. Which is why any Great American Songbook made today won't hold a candle next to one from 1950s.
We're in the greatest era of symphonies IMO, it's just that they're hiding in surprising places; movies, TV shows, games, etc.
I would also point out that composing for a medium like a game or a movie places a great deal of constraints upon the composer, in terms of theme, cost of instrumentation, duration and most importantly: what is safe and palatable for an executive to approve of.
The future is going to suck.
You have just discovered the fully enshittified version of the business model ai companies hope to reach.
If AI displaces human educators, yes, their supply shrinks -- but we can't assume what direction its demand will go.
We've seen this pattern before: as recorded music became free, live performance got more expensive, and therefore much less accessible than it used to be.
What's likely to happen is that "worse" (read: AI) education will become much cheaper, while "better" (read: in-person) education that involves human connection-driven benefits will become much less accessible compared to what it is today.
Most people may be consider it a win. It's certainly not a world I'm looking forward to.
