I've been using when2meet (https://www.when2meet.com/), it's relatively simple and you don't need to create an account or even give an email. You create a schedule and it will give a link that you can share and you can even create a password for the event. It took me a bit of time to get used to the interface, but it's very simple and I find it a lot more convenient than Doodle, without all the useless bells and whistles.

Subhumans should definitely be in that list.

That's an interesting question. On an individual scale it would probably take a while before you see any significant effect. A lot of apps like Uber or Doordash would probably be completely out. Amazon and other delivery services would also be completely out, they are 100% reliant on GPS signal. On a global scale most freight and major transportation services by boats or planes would be highly disrupted. Yes you can navigate a ship or fly a plane without GPS, but the entire system is reliant on GPS and transponders which are linked by satellite connections (IIRC, don't cite me on this). This means we would go back 50 years but with today's traffic, so good luck with that!

For communication satellites, many remote regions would be completely cut off from the rest of the world, but most cities wouldn't be impacted at all.

One thing that we don't often think about is weather forecasting, it is highly reliant on satellite imagery and it has been for a long time.

And I for one would probably be out of a job… Most of my job consists of analyzing satellite and drone imagery. Modern drones need GPS signal to plan autonomous flight missions, so we would need to rely on our very inacurrate manual flying skills.

I saw a stand-up bit where the comedian (I forget who unfortunately) suggested that Olympic athletes should be chosen at random in the general population. It would actually be a much better indicator of a country's health, would probably encourage people to exercise a bit more, and would make the games incredibly more entertaining!
