How do his accomplishments (numerous as they may be) matter if they are only tangentially related to the topic he's discussing? The fact that his take aligns with many others' does not help if they are all outsiders ruminating on hearsay and innuendo about tightly guarded, non-public numbers. He may well simply be echoing the talking points he has heard.
I mean, per the top comment in this thread, he cites an article -- the only source with official, concrete numbers -- that seems to contradict his thesis about depreciation: https://news.ycombinator.com/item?id=46208221
I'm no expert on hardware depreciation, but the more I've dug into this, the more I'm convinced people are just echoing a narrative that they don't really understand. Somewhat like stochastic parrots, you could say ;-)
My only goal here is to get a real sense of the depreciation story. Partially out of financial interest, but more because I'm really curious about how this will impact the adoption of AI.
