+ the obvious fact that it might matter to the kid that they're going to die

(edit: fwiw I broadly think people who want to have kids should have kids)

Hmm, I have exactly one idea. Are you pressing shift+enter to new line? For me, if I do shift+enter

>! I don't get a spoiler

But if I hit regular enter then type >!, the spoiler tag pops up as I'm typing (don't need to wait to submit the question for it to appear)

Are you thinking of

Until Dawn?

(also it seems like I can get a spoiler tag to work in comments by starting a line with >! but not by putting text into :::spoiler [text] :::)

Interesting, thanks for the detailed responses here and above!

Here's a handwavy attempt from another angle:

Suppose you have a container of gas and you can somehow run time at 2x speed in that container. It would be obvious that from an external observer's point of view (where time is running at 1x speed) that sound would appear to travel 2x as fast from one end of the container to the other. But to the external observer, running time at 2x speed is indistinguishable from doubling the velocity of each gas molecule at 1x speed. So increasing the velocity of molecules (and therefore the temperature) should cause sound to travel faster.

(Also, for more questions like this, see this post on Thinking Physics)

If I make the room bigger or smaller while holding T and P constant, v(sound) does not change. If it did, it would be very obvious in daily life.

This feels a bit too handwavy to me, I could say the same thing about temperature: if the speed of sound were affected by making a room hotter or colder, it would be very obvious in daily life, therefore the speed of sound doesn't depend on temperature. But it isn't obvious in daily life that the speed of sound changes based on temperature either.

So now let's increase T. It doesn't matter what effect this has on P and V and n, as seen in the above. So what's left? Increasing T linearly increases the average kinetic energy of the gas molecules (PV and NkT both have units of energy, this is why), and velocity increases as the sqrt of kinetic energy. So if gas molecule velocity is what determines v(sound), then it has to be that v(sound) increases as sqrt(T).

I think this also falls short of justifying that v(sound) increases as T increases.  Why does it have to be that v(sound) increases with gas molecule velocity and not decreases instead? Why is it the case that gas molecule velocity determines v(sound) at all?

Worth noting that the scam attempt failed. We keep hearing ‘I almost fell for it’ and keep not hearing from anyone who actually lost money.

Here's a story where someone lost quite a lot of money through an AI-powered scam:

We can question things, how it went this way or why we are all here with this problem now - but it does not in add anything IMHO.

I think it adds something.  It's a bit strongly worded, but another way to see this is "could we have done any better, and if so, why?" Asking how we could have done better in the past lets us see ways to do better in the future.

This post comes to mind as relevant: Concentration of Force

The effectiveness of force application often depends on its concentration—on whether you can amass locally superior force at the actual decisive moment.

As someone who is definitely not a political expert (and not from or super familiar with the UK), my guess would be that you just can't muster up enough political capital or will to try again. Taxpayer money (in the US at least) seems highly scrutinized, you typically can't just fail with a lot of money and have no one say anything about it. 

So then if the first try does fail, then it requires more political capital to push for allocating a bunch of money again, and failing again looks really bad for anyone who led or supported that effort. Politicians seem to care about career risk, and all this makes the risk associated with a second shot higher than the first.

I'd agree that this makes a second shot unlikely (including from other governments, if it fails spectacularly enough), if circumstances stay about the same. But circumstances will probably change, so IMO we might eventually get more such taskforces, just not soon
