We're used to the forms of hype led, "tech miracle" investor stripper scams now. The resemblance of this cycle to previous cycles is strong; giving a feeling of "surely people won't bit the same bait <i>again</i>?"<p>Under all the hype, there are small but real advances. The "VR" wave led to some better sensors, the "self driving cars" wave led to cheaper LIDAR modules, and a lot of experience with approaches that fail.<p>You'd have never have sold those as the end products for the price that was paid for them, however. The "LLM" wave of AI is as much a product of Nvidia's need for a market as it is any actual advance or novelty in that field. Ask: where's the patents on LLMs?
