Marty Cagan on the Current “Golden Era” for Product Management (Full Interview)

Cagan says: "There are those who build to earn, and those who build to learn"

I relate this to the "Three Horizons"

Third horizon is 'build to learn' - its a research job. Second horizon is 'build to earn' - its a architecture job. First horizon could be called: 'build to prevent churn' to keep the trifecta. Its a defense job.
