It was fun watching a bunch of back and forth blogging between a bunch of smart people quoting a bunch of smart people last week. If you missed it, you might wanna start at the end and work backward.
I only have one tidbit to add. I don't do much with design systems. I work on pretty small teams, all of which have found a system that works that doesn't involve what anyone would call a design system. When we have intentionally wandered in the direction of a design system, we found ourselves not as architects or gardeners, but as zookeepers. We were just documenting what we already had, which was fine as an exercise, but not particularly useful in practice. Again, just for us.
