Whether it works or not matters to the investors. If it doesn't work they've sunk a lot of money, labor, and time into a boondoggle. They want to replace labor, but they want profit too. Businesses aren't just infinite money machines that can keep throwing shit at the wall until something sticks, eventually the investors pull out when they don't see the returns they expected.
That said, it's up to us to make sure the bosses don't ride this out on golden parachutes.
When the economy collapses we need to put them all in prison.
