? you are suggesting that zero musicians are required by society in order for society to function?

I would rather musicians get paid in genres that I can’t stand than see the legion of programmers employed in “social media” and “on line marketing” and other things that keep people isolated and usually angry. Hell of a lot better things re personal and social interaction than having my phone glued to my wallet or my amygdala.

Neither musicians or social media is needed for modern life. Or even online marketing...

You probably want digital payment systems like banking and warehouse management. But I am thinking those sort of areas are only fraction of modern software industry.
