  • I see a lot of people talking about specific parts of 5G but honestly most of them are optional and only some of them will be active at once.

    “Regular” 5G uses the same frequencies as 2G, 3G, etc. The carriers will be moving more frequency ranges of older Gs to 5G as time goes on.

    In general, we can send more data at once because we have better math for sending data. There’s not really an ELI5 that can explain that part besides more math.

    Another part is there’s also more math so that the phones can take turns talking better or split up frequencies better, so they don’t have to re-transmit as much.

    If you’re in hyper-crowded areas, they made a new frequency range that cannot go through walls, but is way faster than the regular ones that we’ve been using. It’s only good for like sports stadiums and stuff, and you almost never use this. It’s called mmwave (millimeter-wave) and you can safely ignore any marketing around it. Not many phones support it yet because it’s useless 99% of the time.










  • I suspect fear and uncertainty plays into it a lot too.

    The world is changing quite quickly. Boomers got to live through the boom of the 70’s, and younger people keep being told about some fictional utopia of the “good old days.” Whatever they jobs they used to do are either automated or irrelevant now. The white cis male power dominance is eroding, and with it a lot of the social advantages they used to get for free are going away.

    So, things are getting worse, and they’re scared and want to do something about it. The problem is, a lot of these people have a zero-sum mentality, where to improve their own standing, they must do so by harming someone else’s standing. The idea that things can be better for everyone with no one losing out just doesn’t exist there.

    Obviously that’s not true, but if you try to convince them of that? Well, you’re just trying to trick them so that you can take from them. It’s an us vs. them mentality. And you surely don’t want your kids to join the enemy’s side, so you do your best to make sure they’re raised the “right” way. And if your side wants to harm you? Well, as long as the others are getting hurt more, it’s still a good thing, because now you’re getting ahead of the others.



  • Only downside with Yubikeys is that you can’t really have backups. The solution is to have two of them, and add the 2FAs to each of them every time you sign up for a new account. It does mean you pretty much can’t have offsite backups though.

    Personally I keep a USB-A with NFC one on my keyring and then a UISB-C one at my desk, which covers every device I have.
