I guess identity and paying creators for content is the primary focus. ie brave.

their definition of web3 is kinda limited as it revolves heavily around cryptocurrencies instead of the more broad vision of web3 that is basically anything decentralized; ipfs, dat, zeronet, etc.

I'm not a blockchain specialist, but I guess you can have native identity / wallet / interaction on a blockchain (like Ethereum) without having to rely on browser extension (like Metamask) !

I wonder if it's an alternative take on payments, such as Apple Pay being integrated into Safari.

It's crucial to UX. Otherwise if you want to buy something you need to switch to the crypto wallet, pay for it by copying and pasting addresses and wait for the other side to pick up your transaction and show confirmation in the browser.

It's so that even more people can lose their crypto coins through insecure/faulty software.

first-class ENS resolution would be nice
