Nuclear energy, like any technology, is in itself "morally" neutral. What is immoral is to impose a grossly uneconomic technology (worse because it was imposed at least in part for military reasons). Nor are renewable energy technologies, in and of themselves, "morally superior." Their superiority was always economic in the true (broadest) sense: their long-run cost to the human ecology is much less. What is immoral is the capitalist politico-economic system, which leaves valuable technologies to languish while wasting huge economic and natural resources for the short-run benefit of dominant vested interests and military parasites.

"When we read on a printed page the doctrine of Pythagoras that all things are made of numbers, it seems mystical, mystifying, even downright silly.
When we read on a computer screen the doctrine of Pythagoras that all things are made of numbers, it seems self-evidently true." (N. Weiner)
