I haven't watched these videos, but I'm interested. Over time I've begun to consider database systems among the most important subjects in CS.

Consider how many software installers are unable to handle a simple system crash. Although it's completely unsurprising, as modern operating systems don't typically provide tools to help with these kinds of issues.
