If they wrote their stuff in Perl, then I would say yes. But, the Google architecture is written in order to maximize CPU efficiency. In 20 years, even that will be moot. 10 years ago, what I'm saying would've been false. Right now, in Perl, CPU cycles almost always do not matter.
My criteria for good software:
Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
