The good news is that these costs are still in exponential decline and will be for at least a few years. The early iterations are costly, but later versions will be cheap.
The bad news is that because we live under Hobbesian capitalism, (a) the high-value target is human labor (i.e., the ruling class is deciding the middle one is an undesirable expense and a competitive threat) rather than ecological harm, and (b) we will probably see Jevons Paradox arms races that almost no one wants as warmongers and billionaires one-up each other.
The technology itself, nevertheless, could very much be a force for good.
