There's a long history of backlash to new technologies.
When movies introduced sound, people asked: "But what will happen to the orchestra?"
The worry was that the orchestra that played alongside silent films would be out of a job.
This worry was valid, of course, but the introduction of sound into movies dramatically *grew* the industry, increasing net employment by an order of magnitude. Jobs like Sound Editor and Sound Mixer emerged.
As generative AI reinvents industries (and likely replaces some jobs), it's worth remembering past reactions to new technologies, and that the pie grew larger.
