The distributed arch prediction with supercomputers farther ahead was correct—nvidia grew from a niche gaming company to eclipse intel and is on some road to stock market dominance all because it puts old parallel supercomputers on single chips.
Neuromorphic computing in various forms are slowly making progress: there’s IBM’s truenorth research chip for example, and a few others. Memristors were overhyped and crashed, but are still in research and may yet come to be.
So instead we got big GPU clusters, which for the reasons explained in the article can’t run large brain like RNNs at high speeds, but they can run smaller transformer-models (which sacrifice recurrence and thus aren’t as universal, but are still pretty general) at very high speeds (perhaps 10000x) - and that is what gave us GPT4. The other main limitation of transformers vs brain-like RNNs is GPUs only massive accelerate transformer training, not inference. Some combination of those two limitations seems to be the main blockers for AGI at current training compute regime, but probably won’t last long.
This story did largely get one aspect of AGI correct and for the right reasons—that its early large economic advantage will be in text generation and related fields, and perhaps the greatest early risk is via human influence.
