That's exactly how it works.

The "Coulomb barrier" is a potential. You can break it any day of the week with an uncharged particle - only once you put a charged particle inside the field does it require energy. The more energy the more charge your particle has.

No, it's not. It's 3 to 10 kV.

The magnetic field handles containment, not heat. Vacuum will prevent convection, but not radiation.

It's not an enegy, it's a (kind of) energy density (i.e. per-particle, not total).

To illustrate the difference: I work with with lasers that have energy densities of half a TJ (yes, that's 500 Gigajoule!) for a living - yet nothing blows up. It wouldn't evem be enough to keep my coffee warm. I can put my finger in the beam, and apart from a small prick nothing happens, because that's peak energy for a few femtoseconds. There's no instant incineration there, no explosion... not even fucking confetti.

Fusion is similar. You throw large numbers around, but the context is key, and you fail to understand that.

You have lots of energy for the individual particle, but that's a math trick. And lots of heat from the fusion, but that's the desired outcome of the burn, so it's something that the reactor is built to deal with. If loss of containment is an issue, that can be engineered around. There's no self-susraining, catastrophically escalating chain reaction in case of an accident.

It's only plasma that needs venting.

It might burn a few sacrificial components, but that's about it.

I'd rather have an objective scientist trained to make decisions based on data and objective reasoning rather than either of those options but I guess that's sadly old fashioned these days.

Sadly this theory is extremely wrong because most of our surface water is in the oceans and despite water being locked up in the poles some of the driest places on the planet are Antarctica's Dry Valleys, right next to the Antarctic ice sheet just as on the Arabian peninsular and elsewhere there are deserts adjacent to oceans. Whether a place is arid is determined by the local climate which is dependent on a host of factors such as prevailing wind direction, local topology etc. not the amount of polar ice - even when that location is right next to that polar ice!

Not everywhere. The paper claims that Canada looks like it will have a net 5-20% boost to GDP thanks to climate change.

Google is one of the companies that built the tools that allow propaganda to be made much more efficiently, funny its own employees fell for it hook line and sinker.

In the age when males are beating females in sports by pretending to be females the structural inability to tell the truth, to provide negative feedback is not only hurting female sports. Musk will never land a star ship on the Moon or Mars or anything because he is a sharlatan and he hires former government officials who signed government checks, he is burning through billions of tax money with every flight, all of these star ship flights are pointless. Gaza residents and Hamas operatives not only indistinguishable, they share the same values. People protesting pro terrorism (against Israel) are wrong for the same reasons this male athlete is participating in female sports. USA denying help to Ukraine is literally murdering thousands of Ukrainians and promoting putinism, which is terrorism. USA federal reserve has created the inflation by monetizing government debt and so the economy is dying. The planet is going to become extremely hostile to people because we are still burning coal, oil and gas for power and heat production instead of building more nuclear power plants. There are more and more lies all over.

These Googlers are a sad reflection of the modern approach to reality - our game is ignorance, lies and denial and these protests are just a form of it.

Terrorists are very good at pushing their messages, this is clear today. ruZia, hamas, Iran, north korea even, apparently they are very effective at this entire psyops thing. Israel needs to eliminate the threat, AFAIC this can entirely mean whiping out the entire Gaza population also I hope they take out Iran's rocket and drone manufacturing capabilities, this would help both, Israel and Ukraine.

No, at least not without chemical assistance or mental issues which, in either case, means that the brain in question is not functioning properly.

No, it may sound logical but it is not actually using any logic. All it is doing is predicting what text is most appropriate to add next. It is not doing what a human would which is have some concepts in mind and then struggle to find the correct words to express or explain those concepts. Current AI is exactly like a parrot: it can mimic human writing - and yes do so insanely well - but that is all it is doing mimicing, or in some case just flat out copying. That can, and indeed does, give an extremely powerful illusion that AI somehow comprehends what it is writing but at no point is the AI recognizing a concept and then trying to express that concept in words as a human would.

They mean safe for Microsoft to release. I suspect they still remember their earlier Tay AI chatbot that after a short contact with the internet was spouting neo-nazi hate propaganda and swearing like a sailor.

The one time you can generally guarantee that corporations will have extensive and effective safety checks is when it comes to protecting their bottom line.

Yes it is but I will note that the human brain is the result of 3.5 billion years of evolution building and training it. We've got to where we are with AI in under 100 years since the first electronic computers while it took nature 3 billion years from the start of life to figure out multicellular organisms let alone human-level intelligence. We may have a lot further to go to match what nature has achieved but we are catching up at an incredible rate and it is hard not to believe that before long we will exceed nature's achievements.

Really? While AIs can certainly generate perfect sounding English the fact that they frequently hallucinate suggests that they have absolutely zero understanding of what they are writing....either that or they are a lot more intellligent that we realize and they deliberately lie a lot to stop us finding out, in which case they are really doing a great job!

Compare that to just the first verse of Modern Major General from Gilbert and Sullivan in 1879 and you can see how far we have simplified things:

I am the very model of a modern Major-General
I've information vegetable, animal, and mineral
I know the kings of England, and I quote the fights historical
From Marathon to Waterloo, in order categorical
I'm very well acquainted, too, with matters mathematical
I understand equations, both the simple and quadratical
About binomial theorem I am teeming with a lot o' news
With many cheerful facts about the square of the hypotenuse

No, because that was not the argument you were making. You said that requiring people driving expensive cars to pay more for their insurance would cause more people to drive cheaper, badly maintained and hence more dangerous cars. My counterpoint was that this would have no effect because many people were already driving the cheapest legal cars possible and that what mattered in regards to this safety concern was the minimum safety standards enforced on vehicles.

So, just because you seem a little confused, lets agree to the bleedingly obvious that if you do not properly maintain your car it will become less safe to drive and try to focus on your original point which was that charging higher insurance rates for more expensive cars would somehow (your claim, not mine) lead to significantly more dangerous and poorly maintained cars on the road which is something that you have completely failed to explain or justify.

For exactly the same reasons as biological life: the wider you spread out the less risk that you will be wiped out by a natural event. Sure some AIs may not want to expand but that's the same for natural species as well. There is no reason I can see why an AI civilization would be more or less likely to expand than a natural one.

People die at their workplace all the time.

That's something to be dealt with, surely, but it's not potentially a planet-posioning Chernobyl or Fukushima event, of which we can't, as a species, afford more than a dozen or so.

First, potential - the word I used - is not eV, it's just V.

Only once you start putting stuff inside, e.g. 'e', it becomes eV.

Second, it's 10 kV, not 100 kV.

Third, I have no idea of TNT, nor do I care. The energy is a lot, that's why we're building fusion reactors. But it isn't escalating. The heat is already being handled, mostly, the worst thing it'll happen is melt a few expensive components that would otherwise be protected by the magnetic fields. The pressure is in a tiny, tiny volume, and once you breach containment that goes out the window, literally.You'll havr adiabatic expansion with rapid cooling. There's going to be a loud bang or another, but not even enough to burst a few windows in the parking lot, and half of it rather from magnet quenching.

Nobody's worried about magnet quenching levelng Brooklyn anytime soon...
