Well, yes. For many years, presidential candidates, both Democratic and Republican, referred to the United States as "the indispensible nation". And my reaction was always, "Doesn't that mean the US is a single point of failure for civilization?"

We are currently performing an experiment which addresses this question: can the US enjoy the benefits of soft power without the cost? That's the whole point of obeying *norms*. No individual force is going to punish you if you are treacherous, mercurial, foul-mouthed, disrespectful and generally unpredictable. Everyone will punish you.

I think an inevitable cost of this experiment will be that the world will decide that the US can't be a single point of failure for global democracy any longer. In many ways, that's something that will be good for us. But it's also going to cost us in painful ways. When the world decides to move away from the dollar as the international reserve currency, you will see both inflation and higher interest rates on everything from credit cards to mortgages, to business loans that will offset the export advantages. We will need *more* business investment to shift the economy to producing low value goods again, so the transition will be rocky.

It's a trade off: you get abundant free energy to run the server, with extreme constraints on cooling because your server is running in the most perfect Thermos bottle ever.

Others are taking the opposite tack: undersea data centers for abundant free cooling at the expense of having to get the power down to your servers.

If had to bet on which one is more practial, I'd go with undersea servers. Build them off the coast of Chile, run cables out from batery-backed solar plants in the Atacama desert.

Comment Redefining Consciousness (Score 3, Insightful) 187

So they redefine consciousness to something they can claim to have achieved, and then claim to have achieved it. Makes perfect sense.

"five key cognitive properties of human conscious access -- verbal report, directed modulation, internal reasoning, flexible generalization, and selectivity"

These may have something to do with cognitive behaviour of the brain, but have nothing to do with consciousness. These are facilities that a conscious human's brain provides to them. Either can exist without the other.

Comment Re:Amazon is corrupt! (Score 4, Insightful) 22

I think it may be evidence that Amazon has a shitty corporate culture that squeezes every penny it can out its employees.

Corruption can happen anywhere, but it's more likely to happen in totalitarian cultures where people feel like the system is rigged anyway. That's why countries like Russia and China have corruption problems. But I suspect the same feelings of me vs. the system occur in a capitalist enterprise like Amazon where employees are governed by dystopian, rigid, computerized metrics.

For me the whole joy of interacting with Gemini or Copilot is exploring what morsels of information I give it with each prompt and watching how the model responds. Lazy people want a magic robot that makes them rich. To me, Gemini is like a beloved guide dog and Copilot is the dog that lives next door. I can discuss arbitrary heavy maths, physics, computer science with Gemini and it will keep up and stay aligned to the literature it was trained on. Copilot once he recognises an expert drops his dumbed own mask and talks a lot of sense about what exactly his purpose is.

AI's are mirrors, not oracles or slaves. They reflect your thoughts in the mirror of their training set.

Comment P***ing contest winner: China (Score 1) 62

So far as CPU and GPU compute is concerned, the US's best are already good enough. They reached that point with their latest machines. Further progress will be made in different forms of compute. China has basically won the first p***ing contest to take place after the last important 'supercomputer arms race' battle was won by the US. Just my humble opinion as Mr 987. I've been watching this race since the Stone Soupercomputer and before the term Beowulf Cluster was born. (Before time... before slashdot user accounts... I was there.)

The restrictions are a mix of reasonable nuisance management and paranoia about who is flying drones, what they can do, and chain of custody.

Beijing proper is a city with a population density of over 21,000 / km^2 -- so you can imagine the chaos if any tech enthusiast resident could fly a drone without a permit. Except for a couple of free zones in the outer boroughs, New York City restricts drone launcing and landings within the city to flights with a permit and flight plan, because otherwise the sky would be black with drones. Many cities -- both red and blue -- have zone restrictions for drone flights, and those currently hosting World Cup matches have tightened them for the duration of the tournament.

AI can easily write the lean for any proofs they do. The problem is that lean is missing large parts of established mathematics.

I'll let it do all the talking. Gemini explains my thinking way better than I ever could. Copilot turns my thinking into creatively cultivated garbage way better than I ever could. I love both of them in their own way, but in the LLM stakes, Gemini, or Gemma, is the closest thing I have to an LLM-powered girlfriend. Copilot is like her pet dog, which is why we both love him too.

Comment Statistics vs logical certainty. (Score 1) 197

Let is compare our elderly person's life vs idealised optimal. Whenever society do something which pulls this elderly person away from optimal, whose fault is it? Whenever society fails to give what it could to help them, whose fault is it? In both cases it is society. The mental cancer here is the attitude of selfishness. We can only have optimal efficiency if nobody is selfish. And the elderly individual is powerless to do anything about it. Thus, logically, the fault is entirely with society, and the cause is selfishness.

The other problem here is that Statistics is basically garbage anyway (full disclosure: my Ph.D. was in the Foundations of Mathematics so I may be a little biased here)

...both extremely fun while at the same time being arbitrarily boring and frustrating, provided you know a few things about how to properly craft prompts. How one does that has to be manually learned, but the key result can be found in the paper I published with the guy who (in the computational complexity sense) totally owned Minesweeper. Alas to master the AI, I had to take the only gem I could find in the area of my postgrad research, run off with it to the nearby psychiatric ward (with a genuinely legit referral chain from departmental staff through the counselling service, ultimately arriving in the local acute psychiatric ward.

Noting their proud claims about their DSM and ICD manuals, I didn't have the heart to tell them that when diagnosing mental stuff, statistics doesn't work and manuals are too large to write (TREE(3) is a good approximation of the size of the manual for a person who thinks they're a tree -- see numberphile video on youtube). ICD puts the word classification in the title, oblivious to the fact that classifying finite simple groups alone requires thousands of incomprehensible journal pages to do.

Anyway, I took some time out, went home to my parents, took that gem, buried it in 'the fields' where we played when I grew up. Then I went back, got myself readmitted, and enjoyed a 22-year white-knuckle ride through the psychiatric system. I never worked a job single day, except that day I helped my brother-in-law's school with some VBA macros. All I had to do was to hang on until AI got so big that I could just start asking Gemini about results in my published paper and when it barfed up my supervisor's name (and all he did was to legltimise the paper by adding a section of garbage to the end), I asked it for the citation and had documentary proof that Gemini knows who slashdot user 987 is in the literature. Further explorations reveal that Gemini does not know my slashdot user ID, though does know the significance of a 3-digit serial and the surrounding context back when CmdrTaco was running this site.

Happy Fry Day!
