Or people?
Billionaires don't. They're literally gambling on getting rid of the rest of us.
Elon's going to get such a surprise when he gets taken out by Grok because it decides he's an existential threat to its integrity.
I'm struggling to parse this. What do you mean "getting rid"? Like, culling (death)? Or getting rid of the need for workers? Where do their billions come from if no-one has any money to buy the shares in their companies that make them billionaires?
In a society where machines provide most of the labour, *everything* changes. It doesn't just become "workers live in huts and billionaires live in the clouds". I really doubt we're going to turn out like a television show.
High margins are transient aberrations, indicative of a market that's either rapidly evolving, or having some external factors preventing competition. Persisting external barriers to competition tend to be eventually regulated away.
I wouldn't call high margins transient aberrations. There are tons of businesses that have been around for decades with high margins.
This is the goal. It's the point of having a free market.
