Over half the price of a median Manhattan condo is a zoning tax. America's affordability crisis is policy-made — ranked by impact: zoning, permitting delays, rent control, then compliance.

The telephone and the light bulb were invented in several places at once, which makes progress feel inevitable. Some things aren't — electric cars had no reason to exist, and neither does what we're building.

Reliable and predictable aren't the same thing. Reliability adapts to the situation; predictability just repeats. The best people and products manage both — stable enough to trust, surprising enough to stay interesting.

In Starcraft, by the time you scout what your opponent is doing, it's too late to change plan. Market trends work the same way — scouting tells you where your existing strategy can win, not which strategy to switch to.
