Right, which is also a great reason to combine the Human with the Tech, this will be more profound when content generation is out of it’s infancy of relying on prompts. I’m a massive proponent of Brain Computer Interfaces to conjoin man and machine, this way you’ll be able to create what you want just by thinking about it, this kind of thing has already been demonstrated in a lab with crude BCIs, so proof of principle is there, Transhumanism+Posthumanism is the meta move. No need to remove the Human, have the best of both.

As for your second point, see above. Our tools are extensions of ourselves. Human beings evolved for tool manipulation, it is in every single way apart of us.
