WHAT IT’S REALLY ABOUT
AI growth boom strains energy, cooling, and business-model fundamentals fast
- AI infrastructure spending is accelerating sharply, with big tech shouldering much of the capex risk and enabling startups to build on top of a rapidly expanding compute base.
- Model access costs have fallen ~99% in two years while frontier capabilities improve quickly, creating a powerful tailwind for AI applications and new product categories.
- Unlike past infrastructure booms (e.g., early-2000s broadband), AI demand is materializing faster due to global distribution via the existing internet and cloud, though leverage and build-out financing still matter.
- Near-term AI bottlenecks are shifting from chips to energy and then to cooling, driving interest in nuclear power, data-center siting, and new cooling innovation.
- AI company economics should be judged primarily by customer value and retention plus efficient acquisition, with more near-term tolerance for lower gross margins given expected declines in model input costs under competition.
IDEAS WORTH REMEMBERING
5 ideasBig tech capex de-risks the infrastructure layer for startups—up to a point.
George argues large platforms can absorb overbuild risk better than prior cycles, meaning many AI startups benefit from infrastructure they didn’t have to finance; the key watchout is leverage in the broader financing chain (banks/private debt/insurers).
AI’s demand ramp is unusually fast because distribution is already solved.
ChatGPT reaching massive search/query volume far faster than Google is used as evidence that AI rides on mature internet + cloud rails, reducing the “wait for adoption” lag that characterized earlier hardware- or network-dependent waves.
Energy becomes the dominant constraint over the next ~5 years; cooling follows.
They explicitly call energy a bottleneck today and highlight nuclear (restarts like Three Mile Island, colocating data centers near plants) plus natural gas siting; Torenberg adds that once energy is addressed, cooling capacity/innovation becomes the next limiting factor.
Expect more pricing sophistication (price discrimination) in AI than prior consumer tech eras.
They contrast Google/Facebook’s limited ability to price discriminate with AI subscriptions spanning low-price geographies (e.g., India) to high-end tiers ($200–$300/month), implying “P” (price) may rise meaningfully even if “Q” (users) saturates near multi-billion scale.
For AI apps, retention and acquisition efficiency matter more than today’s gross margins.
George prioritizes gross retention (enduring value) and organic pull over strict margin purity, betting that model competition will keep lowering inference/training input costs and lift application margins over time.
WORDS WORTH SAVING
5 quotesI think our house view now is that AI is gonna end up like, you know, electricity or Wi-Fi.
— David George
Just trust me when I tell you the cost of the inputs, um, you know, of accessing these models has declined 99%, or a little more than 99%, over the last two years.

The time to get to 365 billion searches on ChatGPT was two years. The time for Google to get to 365 billion searches was 11 years, so it's five and a half times longer.
— David George
I think energy ultimately in the next, call it, five years will probably be the bottleneck, and that's why we're so excited about nuclear and making investments in that area.
— David George
The big component that I, I think most folks have not yet, uh, realized or zoned in on is, is the cooling piece.
