Is this all that happens in 40 years..

Client: "... all this is ok.. but what exactly do you mean by Web 2.0"
before we could answer.. over enthusiastic colleague..
"You heard about windows 3.1 going to Windows 3.11 to Windows 97 rite..its the same.. its an upgrade from 1.0!"
Now I am flummoxed as to what my reaction should be.. but this is not the end.. this leads to a debate between the two..
"Yeah that's ok.. but they took 40 years to go from 1.0 to 2.0..?"
.. wtf.. I am headed outta here!
