My point being that no one should be buying expensive GPUs when you can pick up a few used ones to get started. But for the sake of discussion let's say you do get a blackwell pro 6000 that's now going for $10,000. I can assure you it will not be $150 10 years from now, with the falling price of dollar, demand for AI inference and hardware shortage, it might cost exactly the same 10 years from now...
Unless the bubble bursts and tons of failing AI companies dump used graphics cards on the market.
