"Can play instrument" is almost never good enough to sell tickets, just like "is good with computers" isn't good enough to be a professional programmer.
So, by diverse ways, the market can reassign suitable people to performing. For instance the programmer can go into sound engineering to replace a sound engineer who is now fulfilling an ambition to be on stage.
no it doesn’t happen like that, those who lose marketable value start doing something much less complex like driving taxi. There are numerous examples of such things.
market doesn’t reassign anybody to anything because people don’t change overnight or after some age.
It is one of the primary reasons why many people from the subway times and I’m not having a good time, like rocket scientists becoming taxi drivers
Can't parse your last sentence, but OK: the programmer drives a taxi, a talented taxi driver gets an opportunity to perform music. Maybe I didn't understand your issue and you're really complaining that the surplus programmers will be miserable, not that new music acts won't emerge.
