Nobody even knows what the fuck web 2.0 actually is. CSS? JS? SPAs? Flash? No flash? Rounded corners? Ad blocker blockers? Sevice workers? Sans serif fonts? Lack of "under construction" gifs?
Web 3.0 is inevitable, not because blockchain or machine learning shit is revolutionarily useful, but because whatever becomes popular will end up being called web 3.0 anyway.
Also annoyed at the .0 BS. Maybe it sounded cool and techy in the 90s but if the major versions are already nonsense, how the hell are you gonna have a minor one?
