Quality you can’t generate: AI is only as good as your constraints

AI changed the cost structure of software. It didn't change the value structure. The value is no longer the code you write. It's the taste, judgment, and constraints you encode into the system that shapes what AI produces.

Dave Mosher

A Slack conversation left Doc reflecting on what bug bashes say about the systems we work in.

Doc Norton

Test-driven development is to programming what double-entry bookkeeping is to accounting.

Neal Lindsay

The fundamental character flaw of the software creator is not the misguided belief that they can solve any problem with software. Instead, it is the belief they can understand how their own software works before they create it.

Steve Jackson

We may need a SaaS appendix for Zawinski's law:

Any SaaS platform attempts to expand until it is a social network.
