Well, partially agree.  www and Englebart had done a full hypertext 
system 20 years before and it was very neat.

Newton.  Parts of Newton are very counter-intuitive.  Aristotle said 
that when you quit pushing on something it stopped.  Galileo said, no 
it will continue on forever unless acted on. (Newton's first law). 
To people at the time it sounded ludicrous.  It was obvious that when 
you stopped pushing something it stopped.  Of course, it is a change 
of perspective of what is pushing.

That we find it obvious is just our brain-washing.  ;-)  A study 
reported in Scientific American many years ago found that most people 
were still working with Aristotelean physics.  Intuition dies hard. 
In fact, I would contend that the reason we have science is that 
human intuition is not that good! ;-)  We are wrong more often than 
not!  ;-)
