This post is mostly about Bitcoin and Proof of Work. Currently "Web3" tech is being built on Ethereum, Proof of Stake, zero-knowledge proofs, rollup sequencers, data availability sampling, and multi-party computation. The recent advances are not like the earliest iterations; a harsh critique of Bitcoin is not equivalent to the harsh critique of Web3.
The post is riddled with fallacies. For example:
> Imagine, for example, a world where you're out at a restaurant, or something, and you accidentally drop your keys. Someone else picks them up off the floor, only instead of handing them back to you, they now legally own your house and car.
This framing is ridiculous and reveals either that the author has no idea what they are criticizing, or is being deliberately obtuse. Nobody in Web3 is suggesting you hold all of your assets in a single private key that you physically carry to a restaurant.
The root of this blog post is this:
> it's the sheer absence of any explanation or detail as to what problem [web3] advocates believe they are solving
And this is the primary complaint. Web3 is too vague a term, and encompasses too many unrealistic hype ideas like houses-on-the-blockchain, and the author has not bothered to look further than these claims.
Why not take aim at actual Web3 products that are live today: Uniswap, Aave, ENS. These all fit under the umbrella of Web3 and are able to secure billions of dollars worth of assets while meeting the promised goals: a set of trustless, permissionless, and decentralized tools for transferring and owning value on the internet.
