I heard that you can use a username on Signal instead of your number to get in contact with other people, but I've not heard anything about registering without a number. Can anyone here confirm that this is possible, or has anyone already registered without a number?

@eldersea @jwildeboer @simotranquilli

Thanks for the answer, that's what I originally thought, but then I read from the OP in the above thread that it was possible and wondered if I had missed something, since I haven't been keeping up with all the latest changes.

@nus @freemo

What about quantum computers?

@freemo @kim_harding

That's a reasonable question to ask. I think there's always a role to play for "clean-up" processes which actually work, as long as they don't distract us from the urgent task of cutting down and phasing out fossil fuels and as long as they don't breed complacency with false techno-optimism

@kim_harding

"Part of the clean-up process" is debatable. Carbon sequestration often doesn't work and can even increase emissions, all while greenwashing and diverting funds and subsidies away from more useful environmental efforts.

So yes, the first step is to stop digging and stop burning!
