  • But they don’t have to know who the message comes from, hence why the sealed sender technique works.

    Anyone who’s worked with centralized databases can tell you that even if they did add something like that, with message timestamps, it’d be trivial to find the real sender of a message. You have no proof that they even use that, because the server is centralized, and closed source. Again, if their response is “just trust us”, then its not secure.




  • They have your phone number (meaning your full identity, and even current address), and as the primary identifier, it means they have message timestamps and social graphs.

    Its impossible to verify what code their server is running. Or that they delete their logs, because they say they do? You should never rely on someone saying “just trust us”. Truly secure systems have much harder verifiability tests to pass.














  • I’d like that to be the case, but nearly every US city, no matter the size, is designed for cars. And the connections between cities prioritize highways, not rail. The US might be able to adopt electric cars, but it’ll never be able to create the kind of walkable, bike-friendly, public-transport focused cities, because that would entail pulling up a lot of cities and neighborhoods by the roots. Once that is built up, its nearly impossible to undo it, and your only choice is to add innefficient kludges on top.

    This is why it’s so crucial to do what China and a lot of Asian countries did, and priorizite metro/rail first, and not build your cities around highways.
