As for the Internet improving... well, during its 40 years of age we reviewed some protocols, added some others, but I'm not sure that's what the author implies. The Internet (not the web, the Internet: http://en.wikipedia.org/wiki/Internet_protocol_suite) of today is quite the Internet of twenty years ago.

But still, if you prefer to, we can go down to algorithmic level, where things never age if they're done right.
