I hope it's a good bit cheaper than that, I pay close to $400/mo for electricity and I'm in no way interested in paying anything like that for AI.
It will be cheaper than electricity - but your electricity will become a lot more expensive to enable that!
If it can automate your time by more than that it's a good trade.
Jeeze, what are you doing that uses so much electricity?
I live in Germany where people won't stop whining about electricity prices, and I pay 75€/mo.
