In all this excellent experiment and in the comments here, I can't help but wonder: minecraft is a game made by humans, for humans to play, and it's about (blocky) humans ("of the humans, by the humans, for the humans")

And it seems the AIs weren't so very effective at playing it, at least initially.

So what kind of game would AIs make for themselves to play?

> ... have to remember that it's one day less in non-leap-years ...

How about just remember January 2nd but for the following year as key days. i.e. if you consider January and February 2027 to be part of 2026's "key days year", then you can forget about whether it's a leap year or not (though you still have to calculate what the key day is from year to year).

[Aside - it would be simpler if the leap day were the 32/Dec instead of 29/Feb!]

Noting also that Jan & Feb (of next year) are the same as May & June (of this year), so you get 2/Jan/Y+1 and 6/Feb/Y+1.

There's also the simpler 'atc' from BSD games. Text interface only.

Well, maybe information that is for sale on the open market to anybody that's willing to pay is no longer considered 'insider' information? i.e. trader Jane Doe can't complain that trader John Doe has this info - she could have it too if she wanted.

(edit: not defending this, I find it to be deplorable and disgraces the office of president.)

> ... opposite directions ...

Yes, I'd forgotten that detail. Still, though, chaotic bifurcation could be present with Il Niño and La Niña driving high & low extremes. Same mean, maybe, but with a bimodal distribution?

> Some (e.g. right to repair, sadly) will achieve almost nothing at all.

I'd be curious as to why you say that. I feel that, right now, you would be correct. But if we could move society to a new paradigm where right-to-repair were the default, then cheap non-OEM parts manufacturers would bloom and repairing something would become much cheaper than replacing. Imagine if every object sold had to come with a manual describing how to repair common failures, and a support department to answer for other components.

Personal anecdote: My $700 oven has a microswitch that broke. The oven wouldn't work without it but the replacement part was all of $5. However the vast majority wouldn't know how to repair it.

Expand this to cellphones, computers, tables, wardrobes, cars, tractors and I feel it would have an impact. And... I suppose... my gut feeling is the biggest part of the problem is psychological. People are overwhelmed and don't know what they can do to help. Raising awareness is crucial, but just raising awareness obviously does nothing to reduce CO2 emissions - it's in second order effects when people start thinking harder about what they can do.

Another anecdote: I gave a seminar recently about energy to a small local environmental conference in a nearby town. My starting point was that nobody knows how to talk about energy - we can talk about length, size, weight, cost, speed, age, price, longevity and so, because we know the units - feet or meters, pounds or kilograms, dollars/euros/yen/etc, mph/kph/mps/etc and so on. But ask someone what is a "Joule" or what can you do with a "kilowatt-hour" and you get blank stares. The outcome? I learned of an attendee who drew lines on his kettle for 1-cup, 2-cups, and so on, and now boils only the necessary amount of water. That won't really move the needle on CO2, but it will raise awareness.

I think a 3.5-sigma event being a 1/1000 probability is only under the assumption of random data - a constant climate would deliver more-or-less random data around some mean.

The appearance of two 3.5-sigma events suggests that the data is no longer being randomly generated around that mean, but is instead drifting away from that mean.

More concretely, if all the data were within 2-sigma, then you could invoke the null-hypothesis and refute climate change. Beyond 2-sigma (and even worse two 3.5-sigma events) refuting climate change becomes (much) less reasonable.

I think I'm one of those to whom you refer (except that I'm already "awake", or at least I like to think so). I'm normally pro-EU but this chat control is anathema to me. I'll be voting anti-EU in future I think.

There's a graphic novel by Cixin Liu "The Wandering Earth" where they not only stop Earth's rotation with this method, but also propel Earth out of the solar system (for what appear to be good reasons, I might add). Can't quite remember what fuel they used for the engines.

I've often thought that the target* grid phase should be encoded into a high frequency signal, say at 50kHz. Generators without inertia can immediately switch to the required phase and inertial systems can work towards it or disconnect their outputs if they stray too far.

The problem in my mind is that, as it stands, the signal that everyone has to latch on to is itself affected by load and by different generators latching on with different time constants in a complicated feedback loop. Would having a single authoritative source be an improvement? Would that be a way to eliminate the need for inertia?

*I suppose the "target" phase would probably be based primarily on the output from the biggest inertial systems and take into account their ability to adjust phase and frequency.

> anyone who's using them to actually ship product without a human actually digging into it is opening themselves up to a world of risk.

Maybe it's just me, but it seems that companies will happily take existential risks to get a better bottom line short term. Either you're too big to fail or you've already privatised any profits and subsequent losses (due to the risks becoming manifest) are socialised. The motor industry seems to be particularly egregious in this aspect, but also the food industry, construction industry etc.

Seems to me even governments make the same choices in many ways - cut back health-care, policing, education, public transport and let the next government deal with the consequences.

I'm not aware of the composition of lunar regolith - but if it can be turned into many solar panels and batteries and a few large railguns then wouldn't it effectively be very economical to get any amount of regolith to earth orbit?
