It's still early days. 2 years feels like a long time, but it's not that long.
The personal real-world benefits of the www were real and obvious and constantly improving. What has the blockchain actually done for people on a daily basis?
Dotcom bubble was 1997 to 2001.
Bitcoin white paper came out in 2008, first software release in 2009. With comparable development, we'd have expected an explosion of usage and applications from 2013 already (that didn't happen), and a bubble about 2016 to 2020 (that arguably did happen).
At any rate, the WWW was super useful (and was being extensively used) pre- and during the bubble. You cannot say the same about cryptocurrencies.
(And by the way, during the dotcom bubble there were several companies, such as Flooz and Beenz, offering digital currencies. They're all defunct now. If only they had been decentralised on the blockchain...)
I've been following crypto space for a long time but can't think of any blockchain app like that. Only money making companies are exchanges which make money from fees because of the mania and all the people trying to flip tokens to make big bucks and quickly sell to other noobs, but exchanges are old fashioned companies with centralised databases and Java/.NET codebase, they are not actual dapps.
