I disagree, this is the worst reason to be against it. It's choosing horses over trains. Manual labor over engines, mail over e-mail. It's basically purely egotistical, placing something as fleeting as your current job over the progress of humanity.

It’s incredibly naive to believe that all technological advancement contributes to the progress of humanity.

That's a much easier stance to take for people who are not facing loss of income. If we had wealth redistribution mechanisms in place, I think more people would be pro ai.
