Judgement is the new Taste.](https://christian-kohlberg.de/wiki/urteilsvermoegen): KI hat die Schwelle gesenkt, ab der sich Bauen lohnt.

A weekend of testing, and an answer to the question portfolio companies have been asking me for months. - [Building got cheap. Judgement is the new taste.](https://christian-kohlberg.de/en/wiki/urteilsvermoegen): AI lowered the threshold at which building is worth it. But that threshold was also a filter — and if you remove it without replacement, you now build everything that was sitting in the backlog. - [Trendslop: what happens when you ask a model for strategy](https://christian-kohlberg.de/en/wiki/trendslop): Six leading models, seven classic strategic trade-offs, more than 15,000 simulations — and almost always the same answer.
