That's what is meant with inevitability in this context.
If you want to survive you don't have a choice.
I agree with you in sentiment, however that last sentence contains a deceptive concept in it- who is the collective "we" that would have to do the deciding, and do they have a history of taking such choices?
In a more realistic sense of 'choosing' not to automate, it will largely come from disagreements over the subject itself. It will not be that all humans get together and decide it, but rather that a significant portion of humans won't have any part in it.
But from a pure historical viewpoint, inevitability is a fallacy.
Those entities that don't adopt automation will be outperformed and supplanted by those that do.
It's a similar phenomenon with many technologies. Many people opposed cars, looms, cell phones... what happened to them?
