There is definitely some exaggeration around timelines (2030 instead of 2027) and the industry has a cartel but most of it is real demand. From AI companies that don't have the money to pay for it and probably won't ever receive actual shipments but they locked down contracts ahead of time.
I hope so too, but I'm afraid that if China ever blockades Taiwan, then current RAM/GPU prices will look like an incredible bargain.
Now that's a pretty brave assumption!
There is a Q about how much RAM these phones will need and the average selling price.
People are seriously addicted to doom scrolling. But what are they willing to pay for a phone?
