When this applies
when evaluating whether a historical growth rate in any capacity metric can continue, break it into its independent structural components and check each for headroom
The takeaway
To judge whether a compounding growth trend can continue, decompose it into its independent multiplicative drivers and check each one against its own ceiling.
Why it works
A composite growth rate is the product of multiple independent structural factors; if each factor individually has hard physical, engineering, or allocation limits, the composite rate cannot be sustained once those limits bind.
One level up
Aggregate growth rates are only as sustainable as their most constrained underlying component.
Where it stops holding
This stops working when new structural drivers (not yet identified) can emerge to replace saturating ones, or when the components aren't actually independent/multiplicative.
Detail
procedure:- Decompose the aggregate growth rate into multiplicative components
- Assess each component's headroom against known physical/engineering limits
- Flag components nearing saturation (e.g., wafer allocation to AI going from 60% to 86%)
- Conclude on likely future trajectory of the aggregate rate
benchmarks: {"moores_law":"1.4x/yr, likely topping out","fab_buildout":"1.2x/yr, bottlenecked by ASML EUV machine supply through 2030+","wafer_reallocation_to_AI":"1.8x/yr, N3 node AI share going from 60% to 86%, nearing saturation by end of next year"}
rationale: Each of the three multiplicative drivers of compute growth faces a concrete, near-term ceiling, making sustained 3x/year growth implausible.
In their words
So 1.4x of that is coming from Moore's Law. Far from increasing it, think it'll be a miracle if you can just keep it going for a few more years. 1.2x is coming from building new fabs. This process is ultimately going to be bottlenecked up to 2030 and potentially even beyond by just building new ASML EUV machines.
