I don't know that this is so much an explanation of why databases matter, so much as an assertion of faith that they do. While I would never deny the claim, you could substitute "morality" for database and it could be an excerpt from a sermon.

I care about my data too. I think it is NOT acceptable that Amazon was down last week and all of the services were also down - they should have a backup plan.

This is why I LOVE NoSQL - it promises to disrupt databases by allowing easy replication and sharding. It exposes the fact that CAP is for ALL databases and you can make the choice if you want Consistency, Availability, and Partition tolerance
