You're right - the whole internet thing was a complete failure. I'm surprised you even found a way to post this on the internet.
Hey guise, listen to this genius, internet totally exists just because of the dot.com bubble and all good that came from it.
The point is that the .com bubble was followed by the .com renaissance - arguably the most important 10 to 15 years in human history.
Arbitrary quote form wikipedia:
"A friend of mine has a great line. He says 'Nothing important has ever been built without irrational exuberance'. Meaning that you need some of this mania to cause investors to open up their pocketbooks and finance the building of the railroads or the automobile or aerospace industry or whatever. And in this case, much of the capital invested was lost, but also much of it was invested in a very high throughput backbone for the Internet, and lots of software that works, and databases and server structure. All that stuff has allowed what we have today, which has changed all our lives.
that's what all this speculative mania built.
