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

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

Doc Norton

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.
