If everyone becomes 10x more productive it won’t mean the companies cash flow 10x’s. Where value is loose there is competition, so in theory everyone should win. Unless nobody else can compete to capture that loose 10x value, in which case congratulations, you are now a unicorn.

Of course in reality in the short term what happens is companies lay off people to increase margins. Times will be tough for workers, and equity keeps gravitating towards those who already had it.
