Even if it is 5 or 7 years, houses last decades. Even cars last longer than GPUs. GPUs are a highly depreciating asset. They'll last longer than 3 years, but might not be very cost effective (tokens per Wh) compared to the latest AI accelerators that are available. I wonder if it will be that the U.S. (and allied countries) will be using the latest 1-2 generations of AI accelerators, and if the 3-5+ year old stuff will be sold to Chinese datacenters since that will still be the most powerful tech we'll be allowed to export to them?
