Earlier quoted context omitted.
When the Internet was 10 years old the year was 1987.
Having heard this argument a nauseating number of times, it's fairly clear that people on both sides who say this use "the internet" when they mean "the web." So 1999 is a better "after 10 years'" benchmark here.
I'm also not sure why "the technology is in its infancy and doesn't give us great indications at if it is usable in the real world, but right now is full of scammers and fraud" isn't an acceptable position. Why does it have to either be the next great new thing or a grift? People grifting with new technology and taking advantage of the tech illiterate is pretty common.
