I think it's because humans comprehend and share information in ways 
that look little like the pathways we describe for computers.  I'm not 
even talking about "knowledge", just information.

I recognize that an entire industry rests on believing that the 
'information' computers produce is equivalent to 'information' as humans 
have described it in the past.  I just don't believe that equivalence is 
real.

If your people think like computers, or in this case, prefer to think 
that they do, this description is great.  If I spend too much time 
programming, everything looks like a programming construct.  Step back, 
though, and it's clear that I've just spent too much time talking with 
computers.
