Past history has told us that at least some technologists have
failed miserably in predicting whether fast routers can be built
which handle largish routing tables.

If I recall correctly, an argument similar to the above one was
one of the arguments the ATM proponents used in their day: you
need a short header to do fast lookups, and "fast IP routers
cannot be built".  History since then has at least told me that
this was not entirely accurate.

Therefore, I tend to view the above justification and limits with
a healthy dose of scepticism.
