Like the artisans/craftsmen in many places (especially Japan), hand craft will always carry enduring meaning — machines ultimately can't replace everything humans shape with their hands. But historically at least, they can replace over 99.9% of it.
What about 'machines' with hands and human-level cognition?
That said, this goal might itself be a non-goal. AI is going to be — or already is — more powerful than any individual human in many ways. But what my intuition points to is that humans will still have plenty of interesting work to do, like the author's example of handwriting code: it shifts from being scalable value creation into a form of craftsmanship.
