"I'd google it" is a terrible answer to some questions, e.g. stuff people ought to know like what recursion is. It's a great answer to other questions, e.g. stuff not worth remembering (like API details you use infrequently).

Some things are simple enough you can (re)learn in 5 minutes with google. Others aren't. Knowing which is which is a good skill. Trashing Google in all cases equally is wrong.
