I didn't really get the gist, aside the dotcom is there really any other that didn't experience the up and down nature of the market, just reasoning alone makes me believe the internet would have experience stagnated growth at some point, won't we count that as a down.

Aside it having a stagnated growth, surely there isn't any other way it can go down as people rapidly adapt to using it, I guess all relevant techs acts the same. Speaking of such how come the Nividia a technological based company doesn't represent this, instead it acts like every other stock?.
