Many things on the net may produce dullards, but google isn’t one of them.
They used to worry about calculators. From a technical perspective, Google and the web pages it gives instant access to are nothing short of manna from heaven. I have seen very little to fault the information I find when I get curious about some topic. A lot of the more advanced stuff is held “close to the vest” so you can’t find everything there is to know, but it’s moved accessibility to a new plateau. My grad school professor used to tell us never to accept anything we read in a paper at face value. On the internet, it is merely the illusion of authority that has been lost ... one doesn’t have to be reminded to read critically.
