01What it rests on, and what rests on it

each row quotes the page it rests on

Depends on

  • Grid interconnection queues
    “We have experienced and may in the future experience supply shortages, price increases, quality issues, or longer lead times that could harm our operations, driven by raw material or component availability, manufacturing capacity, labor shortages, industry allocations, logistics capacity, inflation, foreign currency exchange rates, tariffs, sanctions and export controls, trade disputes and barriers, forced labor concerns, sourcing requirements, geopolitical tensions, armed conflicts, natural disasters or pandemics, the effects of climate change, power and transmission availability, and significant changes in the financial or business condition of our suppliers.”

    sec.gov · primary source · Alphabet’s 2025 10-K. "Power and transmission availability" is one cause in a long list.

  • High-bandwidth memory stacking yield
    “Ironwood features enhanced SparseCore, increased HBM capacity and bandwidth, and improved ICI networking.”

    blog.google · primary source · Google’s own TPU. Names HBM, not its supplier.

04Ways to take part

how to reach it, not whether to

Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
