It's qualitatively different, like world-destroying atomic bombs versus the minor explosives that came before. This is not like a loom replacing hand-weaving. We're rapidly converging on a full replacement for the human mind.
These systems will not defeat you with guns like in Terminator. They will defeat you by commoditizing your mind and making your economic value zero.
Our children will propagate whatever it is to be human forward. If the next generation is completely digital/AI/made of silicon then, in my opinion, the most likely scenario is that they will propagate this essence of humanity forward, just like "natural" children would.
In other words, luddites view AI as an invading force whereas I see AI as our children that will propel humanity forward.
In terms of responding to your economic value zero point, I'd highlight that, under normal circumstances, in 120 years yours and mine economic value is exactly zero. The best we can ever hope for, in this scenario, is that we make some contribution that allows us to be remembered. The only hope for the essence of our personality or brain power to be preserved and still be functional in perpetuity is if it's copied into an "AI" or there are some spectacular advances in longevity science that would only be possible with AI.
This is a logical point of view for those who believe they ["human beings"] are merely hydrocarbon based machines twisting in the winds of entropy.
