“We should do away with the absolutely specious notion that everybody has to earn a living. It is a fact today that one in ten thousand of us can make a technological breakthrough capable of supporting all the rest. The youth of today are absolutely right in recognizing this nonsense of earning a living. We keep inventing jobs because of this false idea that everybody has to be employed at some kind of drudgery because, according to Malthusian Darwinian theory he must justify his right to exist. So we have inspectors of inspectors and people making instruments for inspectors to inspect inspectors. The true business of people should be to go back to school and think about whatever it was they were thinking about before somebody came along and told them they had to earn a living.” ― Buckminster Fuller
Why on Earth would you expect something so unjust and unfair? Do you expect to pay a tax to former travel agents when you buy a plane ticket online? Do you pay to descendants of calculators (as in profession — the humans who did manual calculations) every time you use a modern computer?
We have a choice about how society is organized our current setup isn’t ‘natural’ and it’s largely one of accelerating inequality.
There's nothing unfair about it. No person or company is entitled to other people or companies buying their services or goods. Your "source of income" is just other people making decisions with their money. Which they are free to make however they want (as long as they honour agreements that already exist, of course).
Losing that would be a real shame.
Despite that here on HN you have people cheering them on, excited for it. Tech is one of the last good paying fields and these people don't realize it's not a matter of changing career, because there won't be anything better to retrain in.
They are cheering on their own doom.
