You Can't Have Everything You Want | Impossible Trilemmas

Some limits are structural realities, not unfinished problems. Once repeated effort shows that a constraint will not yield, adaptation becomes more productive than denial.

A trilemma is a constraint structure in which three desirable goals cannot all be maximized together. Once you expose the triangle, you can choose the sacrifice instead of letting a hidden default choose it for you.

Speed, quality, and low cost compete for the same finite capacity. Push hard on two, and the third usually becomes the price—even when nobody names the sacrifice.

A society cannot maximize fairness, equality, and freedom simultaneously: protecting free and fair choice permits unequal outcomes, while guaranteeing equal outcomes requires constraining choice, procedure, or both.

In a distributed system, consistency, availability, and partition tolerance cannot all be guaranteed at once. CAP is a mathematically provable trilemma, not merely a difficult engineering compromise.

Energy systems cannot maximize sustainability, availability, and affordability at the same time. The useful question is not how to escape the triangle, but which compromise a system is making—and who bears it.

The existence of evil creates an impossible trilemma: God cannot remain simultaneously all-knowing, all-powerful, and wholly good unless at least one attribute—or the meaning of evil—is revised.

When incompatible goals cannot all be maximized, choose the compromise explicitly. Otherwise luck, randomness, or hidden defaults will choose what you sacrifice.
