Meh, this is how Tech has always worked. The list of companies that foresaw endless growth due to a temporary market advantage is long. As an example ask Intel how their DRAM production is looking these days. They were dominating the market with it in early 70s but by the early 80s they'd been entirely supplanted. Anybody still buying new ZIP drives? How much market relevance does MySpace or Napster have these days?

This particular stock "crash" is really just an investor driven blip that Nvidia will quickly put in its rearview mirror but its a signal flare that the AI Market in general and the GPU market in particular is ripe and waiting for disruption. That disruption is coming and it will arrive quicker than most realize.
