Pretty proud of this one too. We tend to go _wide_ with system observability because cloud. But we don't as often build mental models of wth is actually happening on a single instance. So the in-process stuff could fill a real gap I think

learn skills unlikely to be automated. welding, plumbing, electrical, construction, tailoring. anything that marries brain power and the material world. touch grass.

is a great return to simplicity possible in software? should be fun, simple, transparent, predictable.
