Well, IIUC the actual models generally say more "nuclear autumn". It's still enough to cause massive famines and various other really undesirable effects. (I didn't say side-effects, because they are really components of 'nuclear autumn.)

OTOH, that was the prediction decades ago for a nuclear war between India and ... Pakistan or Afghanistan (I don't remember which).

I doubt those methods give the estimates for 10m below the surface of the ocean. It *is* a short record, but it's what we've got. Also, I don't see any reason to doubt it, except that I'd rather the answer were different.

Still, don't put high certainty in this particular measure. The problem is that it agrees (in general) with lots of other measures that have a much longer span. There are arguments against pretty much every one of them, but they aren't convincing and even so you have to have dozens of special cases happening at once.

You left out informative, but otherwise I pretty much agree with you. The problem is that I expect MANY jobs are going to evaporate. Whether enough new jobs will appear (that are easy to cross-train into) is another question, and I really find it dubious.

We won't find out the answer this year, but we may find out next year.

"Houses" probably predate homo sapiens. They my just have looked like lean-tos, but they did the same job, just not as well. And if you demand mortared foundations, they didn't show up until the very late stone age.

The thing is, when you're mobile rather than settled, a house is a very temporary asset. And they have defects as places that house lice, fleas, etc. So you usually prefer to keep moving. Agriculture is what probably caused what we think of as houses to be created, but the first "permanent" houses were probably organic developments of the pre-existing "temporary shelters".

P.S.: Look into the construction techniques used by Chimps and Orangutans. These are called "nests", but they aren't trivial constructions, and as they're in the trees, their requirements are different from ground based constructions.

That's clearly wrong, as there currently exist (very niche) applications for entanglement. I have strong doubts as to it's wide application, as the conditions for keeping it extant are so severe, but few and niche applications isn't the same as unimportant.

FWIW, ISTM that this might have application to quantum key exchange, I just don't know enough to say yes or no.
