I work in IT, and it’s a similar situation. Bluntly, I Google half of the tickets I touch. I don’t really know shit about how things work specifically. I know the generalities, and the structure in which they function. I have the foundation of knowledge to know what to Google, but the fact is, I don’t remember crap about how to do just about everything.
There’s simply too much to know.
In college, using Google was a sin. IMO, they should teach a class on how to get the results you need from Google because you’re not going to remember whatever the subject is when you need to in six years and you come across an issue which requires that knowledge.
