Most surprising pushback I received about that big Businessweek piece last week was on asteroid mining — people believe its Science-Fiction.

But it is not. This just came out yesterday:https://t.co/uAIy4UJ7H3

Oh, a lot of people believe things are science fiction these days even after they happen. This I find truly bizarre. Quantum computers is a recent example of that. People were saying that they were “impossible” and “science fiction” after teams had built working examples.

We live in a world moving so fast that often working tech exists years before the pronouncements of its impossibility even start being proclaimed.
