I expect we will see GPU rental systems become a thing. There are a lot of high-end GPUs sitting in consumer computers doing absolutely nothing for 90% of the day. Imagine if individuals could allow a training model to access their GPU remotely and in return pay them something in return. Yes, remote GPUs is not optimal, but with the consumer taking on the maintenance, power bill, and ownership of the GPU, any use the training model gets is a net positive.
