How do I own? I mean I realise I can buy NFTs which I guess are "web3" but then I can buy a bunch of stuff on the normal web including stock in facebook etc.
buying a stock on web2 vs web3 gives interesting properties because of ownership.
for ex: take an instant USD loan on your stock, since you are the owner only your authority(signature) is needed. In web2 world you go through middlemen.
I do care if that data gets leaked or if that data is used by third party companies for things I have bought and I do not want them to know. Why should a bank do my credit scoring based on my what am watching on Amazon or what books am I reading
people enjoy reading and writing more than they care about owning their data. I don’t care if my Amazon purchase history is on Amazon servers or mine.
Web3: read slowly - write slowly - vague claims of "ownership" limited to particular blockchains each with no authority over anything off-chain.
But hey, smart contracts allow a long chain of intermediaries to bleed a percentage off all transactions.
