That's kinda like saying people who use postgres understand query performance more than people who use mysql.

I think it's more like postgres vs csv.

This statement strikes me as likely to be true, at least for database non-experts.

It was certainly true for me. I didn't have anything approaching a decent understanding of query performance until I discovered posgresql's EXPLAIN and, perhaps more importantly, EXPLAIN ANALYZE.

I think the opposite. K8s hides so many things under layers of NAT that you really dont understand what does and doesnt work.

The 5-15 issue is a self inflicted wound k8s brings to the party that is quite interesting to work around

k8s hides away some scalability problems and does not address many others.

Most real scalability issues exist on lower levels and require more theoretical thinking than experimenting with tools.
