That would imply that the current AI cycle would be able to persist at its current levels of frothiness indefinitely: In the in-between lull periods, these GPU farms would be seen as something to sell off. This doesn't even take into account the eventual depreciation of the GPUs in question, as better GPUs/accelerators come into the market.

Most companies have an AWS account that they can throw on more money at for 'AI research & implementation'. With such an account existing in the first place, along with said price depreciations, the company in question would have to be certain that they'll use said GPUs all the time to make up for the upfront costs they'll be putting up with.

Your own hardware can be rented out if you're not using it through vast.ai for example.

When new hardware comes out, you can sell old one to recover some of the cost.

Sure bud. Sure. To each their own. When these GPU enter the consumer market is when the AWS cost becomes irrelevant. =)
