Sure. But if that fully depreciates, $1100/year GPU produces $20k of economic benefit, would you decommission it as long as there is demand?
I want to see math on how a single GPU will pull down that much revenue, because that seems like a dubious outcome.
If my data center sells a pflop at $5 because of our electricity use and the data center a state over with newer GPUs sells it at $2.50/pflop, it doesn't matter how much economic benefit it generates, my customers are all going to the data center a state over.
