Which is true, on the long term. But we have no reason to believe that AI will be different in that case. In the short term, technologies have absolutely been used to exploit the average person; the industrial revolution benefited us all over time, but tell that to the kids killed in early industrial manufacturing centers.
Look at how the transition to globalization went in the 80's-10's; entire sections of the US were essentially shut down because of the improvements in communication technology, and unless you're in support of the current state of the US, you'd agree we're still dealing with the consequences of that.
Even in your own case, there's an argument to be made that CFCs meant the overall damage to humanity was greater than the ice trade, just spread out over more people. The exploitation was similar, but it was less visible. Even if we've eventually reached a point where people were better off, you can't argue that the health of the average person was never exploited for the benefit of the few.
To be clear, I'm not separating myself from this; I'm fully aware that work I've done has displaced people. I'm just chafing against the moralizing around it. It feels like the people making these arguments are trying to remove themselves from responsibility while continuing to build on top of companies like Amazon, that are built on top of exploiting people that absolutely cannot advocate for themselves.
