I'm a middle aged developer who spent pandemic time in "web3" (ugh) dev discords and stuff.
There are scammers, sure, but mostly there are a lot of young people who are learning tech in an environment that feels fun and rebellious and honestly a little like the old internet in a way. There is a lot more happening than just people building magic ponzi boxes. It's hard to feel anything but positive about seeing people excited about learning JS or OCaml or Python or Processing.
That said, truly don't understand "web3" and this obsession with things being on a blockchain. It feels like people don't know their Internet history and also I don't understand why DWeb/indie web and web3/blockchain people are fighting since I think they'd be stronger together.
