This statement is deluded and childish. The author is ignorant. There is nothing in capitalism that will guarantee any fair outcome. In fact the capitalist system is designed to make sure fair outcomes do not happen. Markets destroy fair outcomes. Capitalists divvy up the profit pie without any restraint. Capitalists hate restraint. Capitalists kill to be unrestrained. But the author expects fairness. Not on this planet. Not for more than ten minutes before a grifter comes by and smells opportunity. The author likely thinks bitcoin is great too. That shit smells fine.
Anything to take the focus off the system. A.I. is blamed by capitalism for taking advantage of workers the way fascists blamed Jews.
QuoteThe machinery itself is innocent of the misery it brings. The same steam loom that throws the English weaver out of work could be freeing them from drudgery - if only it weren't private property. - Uncle Karl
Marx's Distinction Between Living and Dead Labor
Living labor refers to the active, creative work performed by humans, which Uncle Karl considered to be the sole source of new value.
Dead labor embodies value congealed within tools, machines, and raw materials. Including modern AI.
AI is just another form of dead labor. Like a hammer or spreadsheet AI merely transfers it's existing value and does not generate new value.
As long as the system operates without sufficient checks and balances, all increases in productivity regardless of the source (human effort. advanced technology, hocus pocus, eye of newt, whatever), will benefit capital owners and not the broader working class.

When the trickle-down theory was first promoted, trickle-down stopped. The theory was a purposeful lie. The growing divergence between productivity growth and worker compensation since the late 1970s precisely coincides with the decline in private sector union power, and the start of trickle down blabber.
