Poorly? Almost none.

Well? Significant.

Unhelpful and arrogant. We are amateurs in the eyes of the gods.

It’s very easy to set something up for the first time.

It’s a bit complex to keep something running for a long time.

It’s very difficult to make something fault tolerant with no data loss or corruption.

Arrogance is thinking that these things are easy because you can read a quickstart.

It is true though, but it is also true that a ‘poorly’ run database server is good enough for many use cases. There is a reason people are DBAs and they are very well paid.

Arrogant and foolish to declare no-one can be high skilled.

You're right. But so am I.
