On a spectrum between tulip wilting and fiber build out, we know deprecation cycle of DC hardware leans towards tulips i.e. <10 years (very generous) vs 20+ years for fiber layout, a lot of which is actually infra/earth works etc.
The numbers being cited is ~100B is well within accounting/ledger maxxxing tricks relative to current pool of investment. Luu is not analyzing number's he's just listing and believing numbers, and analytically entirely avoids the core Zitron thesis... once you tap out of easy investor $$$, FAANG warchest, accounting tricks... where is the rest of the order magnitude more $$$ that justifies existing spent relative to time frame coming from?

[1] is a reasonable discussion of DC cost models, which calculates depreciation as part of the annual cost.

That money comes from long term debt (ie bonds by public companies[3]) and new investment into neo-cloud companies (ie, IPOs like 4).
The justification comes revenue. Eg, the NScale IPO above[4] has $51B in long term contracted revenue with an annual run rate of $500M.

This narrow focus, of course some intermediaries in industrial chain is going to make $$$ selling/renting shovels - there is stupendous amount of $$$ being moved around, there will be some very phat winners, but even more losers in aggregate on broad ecosystem level. [1] is actually illustrative, there's a reason why opex low - capex premium is ridiculous right now, with almost everyone along compute industrial chain capturing 50%+ margins. Investors are burning $$$ and companies and pillaging warchests, intermediaries are raking in $$$, but that doesn't mean investors or companies doing all the spending will make more than they spend, i.e. the net ecosystem business model is not sustainable precisely because intermediaries are capturing crazy rent relative to actual monetization to sustain.

You understand that this doesn't follow at all right?
The intermediaries margins can compress.
> opex low - capex premium is ridiculous right now
What does "capex premium" even mean?
Of course you spend more on capex when you build a data center than opex!
High capex matches the expected business model. If opex was high then everyone would be worried!

Counterargument: As advancements in transistor densities slow down, the rationale for increasing depreciation cycles makes more sense. As the performance gap between new & 5-year-old hardware continues to shrink, then the need to replace older hardware similarly shrinks, justifying longer depreciation cycles.
It's not just about node advancement, which is coupe de grace condition. Even if hardware advancement freezes, its about IC premium that fed current tranch of AI buildout. Current players paid $10 for a $2 hammer due to premium, a better future hammer might cost $3 but does twice the work of $2 hammer. That is like ball park the premiums we are talking about - from gpu to memory to other components getting inflated due to exuberate AI demand.
The economic logic is if current spend vs revenue gap is not sustainable... hardware prices / margins will revert towards mean. That $10 hammer will be compared against a $2 identical hammer (margin reversion/compression)... or worse, a $3 future hammer that does $4 / past $20 of work. The future player who only paid $2 can charge much less... i.e. simply paying $10 limits ability to price competitively. The future player who pays $3 has 50% more compute than incumbent who paid $10. The important DC TOC consideration, is in world where DC cost regress towards mean, opex > capex... so merely continuing to use that old $10 hammer is losing MORE than buying a $3 better hammer, i.e. the asset is economically stranded, it is COSTING MORE to run old hardware than simply buying new hardware. It's MORE than economically useless and $10 past purchase price not just sunk cost but dragging down balance sheet as amortized liability aka it is full write down / loss.
