While I am skeptical

of this new technology you refer to ever coming to be, that doesn't really resolve the problem.

Even if it were productive beyond the wildest dreams of its proponents, you'd still eventually run out of productivity increases. Malthus was just early, not wrong.

Not to mention the massive danger of 100 billion people being dependent on some technological gimmick that let them live off Earth's crust. Fragility increases with such leverage.

Finally, regardless of these practical questions, the philosophical question remains whether human life would continue to have value in the event that the marginal human being had zero or negative net (beyond subsistence) economic value. On naturalism, it's hard to see there being any objective value of a human unit.
