  • Ah, probably so - I have no idea how long in absolute terms it takes to reach any given amount of fluency, but my thought was that they noticeably still have a way to go - which I figured was why they asked, to get a straight answer on that.

    I also have no idea how it’s evaluated or what system those level labels are part of.






  • I read it. Doesn’t mention FTL, because that’s not a possibility for actually transmitting info.

    Edit: I think the way these quantum encryption systems work is that basically the photons (and I assume it’s polarization being measured) become the encryption key to a message that is sent conventionally.

    Like the sender generates a bunch of entangled photons, sends the paired ones to the recipient, measures their photons and uses the results to encrypt the message, the receiver measures theirs and gets the same results, the sender sends the encrypted message over email or whatever, and the recipient has the same key because of entanglement.
    Meanwhile an eavesdropper measuring the photons would mess them up for the recipient so the message wouldn’t decrypt.





  • Roller skating. I’m super unathletic, but skating (including teaching to others) was listed in the profile of a girl who contacted me on a dating site, so after chatting for a bit I suggested that as our first date. She was super patient with me, I had never put on skates before that day, and was in my 30s.

    We’re married now, and I now also teach skating where she does on weekends, sometimes to people who have never tried it before.




  • The issue (as the link illustrates, but I didn’t go into detail) comes with long distance communication. Time zones serve as a rough approximation for ‘where is the sun’ at a specific place that you want to communicate/trade with and that is a rough approximation for 'when are people/places likely to be awake/open. Without that you Would need to find published hours for people/places and that can be tough.

    Replacing time zones isn’t impossible of course, but it’s definitely not as simple as ‘just use UTC+0’. That shifts the inconvenience elsewhere
