I dunno - I am a bit ambivalent about this.
The knowledge base of yesterday and today is quite different. I have a reproduction of the first Encyclopedia Brittanica, and it is only three volumes. It did not have any "awareness" of astrophysics, NASA, cars, jets, washing ones hand removes germs, etc. It was the sum of general human knowledge, and it was very limited.
It has been said that the web is fundamentally changing the way humans think, and I see some truth in that. People don't remember/memorize things - they have a personal library in their hands. Personally, I had close to an eidetic memory that served me well up until my 20th year in high technology. At that point it became more important to be able to learn something new, quickly, than to remember crap that had long since gone past it's shelf date, and I made the conscious decision to not try to remember everything. Now I have an advanced case of CRS, and that definitely includes the number of pecks in a bushel!!!
That being said, attention spans are waning, and critical thought (don't get me started) is on the decline. People find a information portal that they like and they stick with it, facts be damned. On the other hand, if you want someone to program your Tivo, get a teenager to do it!
I also have a feeling that people like Ben Franklin would make mince-meat out of today's "thinkers"...
A lot of what we do today was magic a century ago, and the "context" of life has changed dramatically.
Like I said, ambivalent.
