sign-in with ethereum is actually a terrible idea because it trains people to sign messages all the time & creates _signing fatigue_. what you actually want is the exact opposite. a sig should be considered _dangerous_ and treated as a _special event_. it should not be something users do casually as part of their normal workflow. if people get used to clicking "sign" everywhere, they stop paying attention & eventually sign things they do not understand (this happens every minute in this space btw). the right security model is to teach users that signing something is a _serious action_ that deserves a lot of scrutiny, and not to normalise it as just another login button. we should immediately stop doing this shit.(sudo rm -rf --no-preserve-root /)
