Finally, honesty. I appreciate that the author understands this, even if they might not have the exact knowledge required to substantiate it.

My fictional-universe theory (FU theory) shows that a knowledge base cannot know whether its facts are describing the real world or a fictional world which has lots in common with the real world. (Humans don’t want to think about this, because of the implication.)
Nuclear power has fairly predictable amortized returns. I imagine that this is worth the cost to MS over the next two decades or so; we have no idea what their current energy premium is like, and this plant doesn’t have to be as cheap as a new plant, just cheaper than the current premium.
