There are no more miners to acquire, though. Manufacturing of these chips is the bottleneck right now, as far as I know.
But inevitable to happen, again if the price skyrocketed. As a great economist once said:
But, there's a fundamental economic law which has never been contradicted to the best of my knowledge, and that is, if you pay more for something, there will tend to me more of that something available.
Who's ironically questioned by Satoshi Nakamoto in 2009, as this law doesn't apply in bitcoins due to difficulty adjustments.

But it does apply in ASICs and everything else!
I believe they would shut down their business, sell the ASICs to people who have access to free electricity and the machines would keep running.
Free electricity? You mean to those who mine with renewables?
