I wouldn't say it's technologically inferiot. I'd say it's less mature. Making desing choices is OK. The authors admits that relational databases have different design goals and thus comaring them directly is necessarily comparing apples to oranges. What is true and wise is that non-relational databases have been around for much less time, have less theoretical background, the development teams and DBAs are less experienced with them, etc.
