Lots of attentions are now on GPU residual value. I find car analogy to be useful.
* Both new and used cars can do the same job (you can run the latest model on 6-year-old A100) * New cars are more efficient (higher performance per power draw) * It's not the year, but mileage and maintenance
The last point is undeveloped. We need Carfax and KBB for GPUs.
