It really depends on what you're buying. Also, 15 years of 3.5% compound interest is not negligible.

The planning starts NOW. That will include rules governing construction. The AMOC stopping hasn't happened yet, and there's no firm estimate of when or even whether it will happen. If they start planning NOW, including changes in the rules governing construction, then handling the housing should be doable.

Also, doable doesn't mean easy or convenient. But the food supply is critical. So is the durability of their power generators. If they can't live there, they'll need some other way to adapt.
(Actually, I'm rather sure that housing is doable, since people have lived on snow fields since before the iron age. Snow based construction has a long and successful history. OTOH, I don't recall it ever being mixed with electricity.)

It's not just the immune compromised. Vaccines aren't perfect, and the only reason they're so effective is that they enhance "herd immunity". They decrease the probability of catching the disease if exposed and also decrease the probability of spreading it to others once you catch it. So if nearly everybody is vaccinated, they're pretty effective. If only a few are vaccinated, they're a LOT less effective.

If the summary is correct, there's no evidence because the FDA refused to provide any reason. So what evidence would you expect Moderna to be able to provide?

Yeah, that was a poor analogy. It's more like "since the last ice age". If the AMOC collapses, expect Iceland to become completely surrounded by sea ice, without gaps. It'll take awhile, but that's what to expect. (But you probably won't be able to ski from Iceland to Greenland.)

OTOH, expect this to eventually cause the Bering Strait to freeze solid. (I said "eventually". This would take awhile.) Also the US east coast would get a lot colder, though nothing like Europe. There's no really good historic model. We're in an ice age, astronomically speaking, it's only the CO2 that's been keeping glaciers from growing. But we've way overdone the CO2. The oceans are acidifying AND warming up. When they get warmer, they hold fewer dissolved gases (like Oxygen, Methane, and CO2). And it's happening too fast. When the oceans hold less Oxygen, it's harder for the sealife to breathe. ETC.

I don't think it's going to shut down the thermal conveying outside of the North Atlantic. The AMOC is just a part of a much larger system. But my *guess* is much of the heat would end up in Antarctica rather than the North Atlantic. Europe would get extremely cold, and Antarctica would melt faster than predicted. (Once upon a time there were forests in Antarctica. Of course, the other continents have moved since then.)

I'm pretty sure you'd have at least a decade before things got THAT extreme. Urgent planning needed, but the construction should be doable. Food seems a more difficult problem. Also, most geothermal plants have a relatively short lifetime. (I'm not sure about the ones based around volcanoes. I don't think those have a track record.)

But they wouldn't identify any specific problems. I.e., they're lying.

The normal strategy is to take them on one at a time...and have the expectation that after you've won a couple, the rest will start to fall in line without being sued.

That's the wrong problem. He's almost certainly planning to loft multiple satellites with each launch. But there are other problems it's reasonable to be dubious about.

I'm going to wait until he's launched a few to form a definite opinion...though I'll admit that I consider it unlikely.

It's possible that he's got an answer to that problem. I'll wait to form an opinion. (Yeah, I'm skeptical too, but I don't think one should be certain based on the available evidence. Also, there are several other potential problems, but maybe he's got answers.)

I think the correct answer is "you don't use a screwdriver as a hammer". Used correctly, AI tools can be quite helpful. But reports seem to show that only around 20% of companies use them correctly. (According to at least one report they produce a 5% improvement for one particular task. Whether that includes the cost of use, the article didn't say.)

You misunderstood me. It was Sony I've been avoiding.

OTOH, Chinese might be better than Sony. They sold their souls so long ago that I can't remember the last of their products I bought. Once upon a time they had a name for quality, but then they sold their soul to Hollywood.

FWIW, primitive savages are generally extremely charitable to others in their tribe. It's people who live in larger groups not as closely related that tend to be more selfish.
