Just intonation may also play a role in the blues. There is a theory that the blues originates from the natural overtone series of I and IV. If this is true, then the characteristic chords and scales of the blues are really 12-TET approximations of the original just intonation blues scale.

For three years I ran Elasticsearch on a side project that had exactly 200,000 documents and about 800 daily active users. Three years. One cluster. Two nodes. Somewhere north of $120/month in hosting costs. It could handle everything I needed — full-text search, faceted filters, typo tolerance — but operating it felt like maintaining a small spacecraft. JVM heap tuning. Index mapping migrations. Cluster state corruption the one time I ran a snapshot at the wrong moment. Yellow cluster health that would persist for forty minutes and then inexplicably resolve itself.
