@eestileib @webology @osma @raganwald I am not sure GPU value expires in 2 years, Google has already shown they have 5+ year old TPUs that are still fully utilized, I am not sure if Nvidia's chips can last as long as under load.
Without a doubt in the world of AI there is a lot "financial engineering" going on, which at some point will shake out, ala 2000s web.
