That depends how much it's used, I suppose. Ever-increasing, it looks like. At some point it might be worth investing in more training to reduce operating expense. Pretty standard CAPEX vs OPEX calculation. On the other hand, we're not counting energy saved by people using it.. What if some scientist uses it and ends up solving fusion power? Or, say, making copywriters and programmers redundant (who I assume would go on to become subsistence farmers) - many energy savings to be had!
