> "people who've studied computer architecture" - which most application developers never have

If you are developing an DBMS and haven't studied computer architecture, the best idea is probably to ask more experienced people to help out with your ideas.

From my limited knowledge, I don't think the article is old enough to be obsolete, just that there's a lot more to it.

Not to be gatekeeping or anything, but it is a pretty well studied field with lots of very knowledgeable people around, who are probably more than keep to help. There aren't too many qualified jobs around and you probably have a budget if you are developing a database commercially.
