This is a great article, and I pretty much agree with everything in it. However, I want to comment on a bit of the discussion about hammers and carpenters in the comments on HN. Let me put this briefly - carpenters learn about wood way more than they learn about tools. Knowing how to cut wood, bend wood, fasten wood, use wood to hold things up, make wood look nice, etc. Those are things carpenters do and learn about. The tools are secondary. Also, one final note - carpenters don’t really use ball peen hammers - those are for metalworking. Carpenters use claw hammers because the claw removes nails.
