I think the concern in this case is that, unlike before where machines were built for other people to use, we’re now building machines that may be able to use themselves.
Not that much of a difference tbh. If one traditional machine allows one worker to do the work of twenty in half the time, that's still a big net loss in those jobs, even if it technically creates one.
The real issue is that AI/robotics are machines that can theoretically replace any job -- at a certain point, there's nowhere for people to reskill to. The fact that it's been most disruptive in fields that have always been seen as immune to automation kind of underscores that point.
In the old times, this was a "want" because the only people without work were those unqualified or unable to work. In the new times, it will be a "need" because everyone will be unemployed, and no one will be able to work competitively.
