               | Reading this line, I had a funny image form of some
               | NVidia PR newbie reflexively reaching out to Lisa Su for
               | a supporting quote and Lisa actually considering it for a
               | few seconds. The AI bubble really has reached a level of

       | 
       | For context, my understanding is that companies have recently
       | moved to mark their expected GPU deprecation cycles from 3 years
       | to as high as 6 which has huge impacts on projected expenditures.
       | 
       | I wonder what the step was for the Blackwell platform from the

           | understanding is that the old 3 year replacement cycle had
           | more to do with some component, not necessarily the memory or
           | the processor, going wrong for half of their units by 3
           | years, at which point GPUs were cheap enough and advancing
           | faster enough that it was more cost effective to upgrade than
           | to fix. However, that calculus changes completely when the
           | GPU and the HBM are orders of magnitude more expensive than
           | the rest of the system. I suspect that we will see repairs
           | being done on on the various brittle bits of the system and
           | the actual core expensive components will continue to operate
           | much longer than 3 years.
