The future trajectory of AI isn't tied to Nvidia's stock in the same way the web didn't thrive or die on Cisco being the most valuable company in the world 24 years ago.
Even if that doesn't happen, there will be a lot of consolidation and bankruptcies when AI funding dries up when category winners become clear and investors cur their losses - the same happened suddenly when the dot-com bubble burst, and little more gently with "web 2.0" startups
If no training breakthrough occurs, then your second option is much more likely.
I was thinking along the lines of how Sun Microsystems and big-iron were dethroned by good-enough commodity x86 servers + Linux. The two coexisted... for a short while.
Much of the problem with PC software at the time was one of scaling. Getting software to use multiple processors effectively took decades, but the cost difference and ability to actually get the hardware cheap allowed it to win the market... then grow back into systems with hundreds of cores and terabytes of memory because the needs for big iron didn't go away.
With AI/training/LLMs/NNs scale, at least appears, intrinsic. We see this in the animal world. We see insects with a very basic brain capable of interacting with the world and surviving. Then we see mammals with larger brains capable of far more as the scale/complexity/interconnectivity of their brains increases. At least from what we can tell, throwing more power at any given problem will give us a better solution.
I really shouldn't have to explain how this bubble ends.
Recognizing value isn't "Rabid fanaticism" lol.
Second:
> allow me to assist in your understanding of the bigger picture: large funds use VCs as money mules to increase Nvidia GPU sales through investments in AI startups and this is not sustainable.
You have to be trolling (or I'm misunderstanding?) if you're arguing that a large proportion of VC investments are at the direction of LPs who are long NVIDIA, for the sole purpose of furthering that long.
> if large funds are unloading their shares, if executives are cashing out their stock options, who is left to buy the bags?
Literally the buyers purchasing the shares that the large funds and executives are selling.
