I think people are just saying that if you don't undertstand the technology a little bit yourself you'll never know who to hire. Maybe somebody looks like they know what they're talking about, but they don't. Maybe somebody really knows what they're talking about but they can't put that across very well. Maybe someome is simply unscrupulous and wants to milk you dry and will dazzle you with charts and graphs that they know you don't quite understand.

It's, like, inadvisable, to leave yourself vulnerable like that.
