Why my CI got 4 minutes faster

I trust monorepos more in the second year than I did in the first. Most of the early friction goes away once the tooling catches up.

Every time I revisit a project after six months, I find at least one place where past-me wrote a comment that present-me has now stopped trusting. Comments rot faster than code.

The team I learned the most from didn't have great tools. They had a great habit of reading each other's pull requests in full, including the parts that weren't theirs.
