This is exactly it. There's a lot of conspiracy theory in this thread without realizing that it's just what happens when an insanely large amount of capital is deployed: market distortion.
It's not just RAM, it's things like gas turbines and power transformers. I've seen suggestions that it's even affecting housing starts because the construction effort is pulling in workers, especially electricians.
However unlike you I'm not of the opinion that all that can be built, in that short timeframe. Even less so that it can be operated without pushing us over the 2C global warming threshold.
What does that even mean ?
The cost of AI itself (tokens/$ for a given level of intelligence) has been falling rapidly, and shows no sign of stopping.
The AI pure-play companies like OpenAI and Anthropic are presumably in worst financial position, since others like Google, Microsoft, Amazon and Meta (also Alibaba, Baidu, Bytedance, Tencent, Xiaomi) have generally been more conservative and are treating AI as an incremental revenue source not a highly leveraged all-in bet.
