The growth itself do not cause the problems, but in conjunction with the

in the router implementation cause the problem. If we look around, we'll
see existing computers (including embedded ones) have not CPU and memory
problems, and all problems we see with the routers are mainly caused by
the bad implemented text.

I, and the rest of the Internet community, would like to invite you to start a
router company and show us how it can be done with far less memory.

More seriously, you might take a look around and note that there are not a
great deal of difference in the amount of memory needed to support a prefix
across the various well-known implementations.  Which is not to say that we're
blameless, just that a lot of good people have worked hard and are all equally
incompetent at conserving memory while simultaneously producing a scalable,
stable, feature-rich implementation.
