1) Web1 was the fruit of academia and unix neckbeards
2) Web2 was the fruit of web developers and silicon valley finance
3) "Web3" was the product of MBAs and finance bros
You can see what's wrong with Web3. Silicon valley finance just wanted to get rich quick too, but they at least had to go through technology and programmers to get there.
"Web3" was pushed by MBAs/Wall Street (at best) and shady crytpo finance bros (at worst), and had little in "new technology". The technology that WAS used came from the Web2 era with bitcoin.
The real "next web" is in things like Mastodon (and Bittorrent and MAYBE some cryptocurrencies around distributed storage). Community or emergent things. Web1 was like that. Web2 was less so, and Web3 almost not at all.
What made "web3" actually stick a bit in the zeitgeist was the emergent nature of Bitcoin. It was distributed, networked, it didn't have controlling company, or even any real celebrity originator aside from the pseudonum "Satoshi Nakomoto".
Web1 was the maturation of TCPIP, networking, and basic text documents
Web2 was a powerful standardized browser and more general purpose UI/computing.
Web3 the hype was distributed and encryption, but has failed to produce utility to the average person, or even the average developer.
Web2 only hit its stride in the post-dotcom crash when the money got back out. In a way, the dotcom boom funded the real Web2, then the crash weeded out the get rich quick people, and Web2 was built on the hardened survivors.
Maybe "Web3" will similarly survive and thrive from a crash that weeds out the scammers.
