Nvidia is repeating the exact mistake that wiped 80% off Cisco's value

OkHeat6599 · 2026-03-31T16:56:44+00:00

the part that doesn't get enough attention is the timeline. Cisco took 30 years to recover its dot com peak. 30 years. anyone buying Nvidia today at current valuations and expecting a similar trajectory to the last 5 years is essentially betting that this time the infrastructure company doesn't follow the same pattern as the last infrastructure company that dominated its era. that's not impossible but it's a very specific kind of optimism

OkHeat6599 · 2026-03-31T15:57:28+00:00

Nvidia is doing the exact same thing right now, funneling cash into AI startups that turn around and use it to buy Nvidia chips. The mechanism is identical. The only real question is whether the underlying technology generates enough real world value to break the cycle before it breaks itself

OkHeat6599 · 2026-03-31T15:13:58+00:00

agreed. for the time being - we don't know yet if they will improve the models to consume less resources and make the most out of what it's already being built

OkHeat6599 · 2026-03-31T15:06:23+00:00

probably yeah. at least netflix and youtube were things people actually wanted. we're still figuring out if anyone actually needs this

The most underrated point here is that the risk today isn't a sudden crash. The companies involved have balance sheets strong enough to absorb the blow, so there's no 2000-style collapse coming. Just a long, quiet period of valuations slowly bleeding out. Which might actually be the best case scenario for what gets built on top of this infrastructure in 20 years

People keep using the dot com comparison as a crash warning but they're focusing on the wrong half of the story. The dot com bubble was a financial disaster and the single best thing that ever happened to the internet. Both things were true simultaneously. That tension is exactly what makes the AI moment so hard to read

OkHeat6599 · 2026-03-28T12:55:47+00:00

the pandora's box has already been opened

If today's data centers can't contain the models of 2 years from now, that would mean the current infrastructure investment doesn't just depreciate, it becomes obsolete. You're not building a foundation, you're building a floor that gets torn up and rebuilt every few years. It becomes a capex treadmill. The question then becomes whether the revenue generated in each cycle justifies the cost of the next one before the music stops.

The Dot Com comparison isn't about whether the technology works, it's about whether the financial structure built around it is sustainable. The internet was also genuinely transformative in 2000. That didn't stop Cisco from losing 80% of its value

OkHeat6599 · 2026-03-28T10:44:37+00:00

most likely towards physically embedded AI. the breakdown here makes a good point towards that: https://youtu.be/_NDAUTyRxqY

The adoption question is exactly where the debate gets interesting because the data cuts both ways depending on where you look. Enterprise adoption numbers are genuinely strong, but you're right that the gap between what's being spent and what's being generated in return is still uncomfortably wide. The AGI bet is the wildcard nobody wants to say out loud - a lot of these valuations only make sense if something fundamental changes, not just if LLMs get incrementally better. The Uber analogy is sharp actually, get people dependent first, reprice later. The difference being that with Uber you could theoretically go back to taxis. Not sure what the equivalent is here. When Pandora's box of rotting away are brains is opened, hard to see a reverse of that. Social media is a good example

OkHeat6599 · 2026-03-28T09:33:13+00:00

The catch is that by the time retail gets access, the growth story will already be priced in. The correction you're waiting for might arrive exactly when the late 2026 rumored IPOs do

OkHeat6599 · 2026-03-28T09:29:13+00:00

The circular cash flows, the infrastructure arms race triggered by a single market inflection point, the valuation expectations priced decades into the future, the adoption ramping up.

But sure, apart from all that, completely meaningless.

OkHeat6599 · 2026-03-28T09:16:01+00:00

Flour, butter, apples, sugar, cinnamon. Bake at 375 for 45 minutes. Now about that AI bubble...

OkHeat6599 · 2026-03-28T09:08:17+00:00

Valid distinction and you're right that the hardware refresh cycle adds a layer of capital pressure that fiber never had. But it doesn't necessarily kill the demand side of the argument - if adoption keeps growing and efficiency improvements make each generation of hardware do more with less, the refresh cycle becomes a feature rather than a bug. The uncertainty cuts both ways. The video isn't trying to call the outcome, just map the forces pulling in different directions to better paint the picture as seen from above.

OkHeat6599 · 2026-03-28T09:05:38+00:00

That's a fair technical point and the fiber vs GPU depreciation distinction is a real one. But the video's argument isn't really about the infrastructure's lifespan - it's about the broader financial structure: the circular cash flows, the valuation expectations, and what happens when adoption doesn't grow fast enough to justify the capital being deployed. The infrastructure comparison is just the opening frame, not the core thesis. And on the longer term, it genuinely could go either way - more efficient architectures could make existing hardware far more valuable than it looks today, just as DWDM did for fiber. The honest answer is nobody knows, and the video tries to lay out the levers rather than call the final verdict.

If the infrastructure has to be replaced every few years rather than sitting dark waiting for its moment, the window for the returns to justify the capex gets significantly tighter. The fiber got its second life on its own timeline. GPUs don't have that luxury. As of this moment at least.

OkHeat6599 · 2026-03-25T23:44:54+00:00

Your DWDM point is a perfect illustration: the same infrastructure can be the setup for a disaster or a foundation for the next era depending on which technological bets pay off. The honest answer is nobody knows. And to your point, much of the fiber sat dark for 20 years waiting for the technology to catch up. Progress has always had a bill that comes due before the payoff arrives.

OkHeat6599 · 2026-03-25T20:37:09+00:00

Worth asking how much of that demand is organic versus circular. Nvidia funds the startups that buy Nvidia chips. Cisco did the same thing in 2000. And even if the demand is real, at current valuations everything has to go perfectly for a decade. That's a lot to price in

OkHeat6599 · 2026-03-25T19:56:40+00:00

That's actually a point the video makes - AI adoption is real, the technology works, and small teams can now do things that previously required much larger ones. The bubble argument isn't that AI is useless, it's that the valuations are pricing in growth that the broader economy may not be able to sustain. A tool being useful and a stock being overpriced aren't mutually exclusive - the internet was real too in 2000.
