Also, the trades have a lot of grabass associated with them. After getting out, I was not pleased to learn that, for better or for worse, blue collar working culture is interchangeable with enlisted military working culture. And not the fun Stripes/Down Periscope part, I mean the G.I. Jane/Jarhead parts.

Of course, there's also the issue of finding the right trade. If you did pneumatic controls or drywall, well, sucks to be you! Should've picked lighting systems, idiot. Oh, wait, Lutron owns everything and underpays its lighting techs. Well, you should've invented a time machine, idiot.

But yeah, trades solve everything. If everyone did a trade, the wage stagnation that happened with liberal arts and STEM totally won't happen with blue collar work. You see, by picking up a wrench or a multimeter, you put up an anti-job competition field that can permanently deflect any number of hungry applicants, no matter how much you get lowballed.

Yes, modern devices use a magnetometer to determine the direction of the North. But with a GPS you know your location relative to the magnetic pole and you can determine your direction of travel using the magnetometer and software to correct the magnetic pole drift. So GPS can tell tell you your direction of travel, albeit indirectly by correcting for your position relative to the drifting magnetic pole.

>This leaves precious few new members in the trades needed to fix our cities, bridges and railroads.

I love how people talk like capitalism is just going to give them the society they want because they asked nicely and it would be mean if capitalism didn't.

Don't forget to vote. That will bring you the society you crave, lmao.

AIs understand. Human brains learn concepts by forming a bundle of neurons dedicated to the concept of (lets say) "cat" based on the input of our senses - sight, smell...Modern AI's are designed to replicate the same process 1 to 1 on a software level. If anything they understand basic concepts better then humans.

The big jump right now is AIs understanding the relationship between concepts. Example: "cat" should be linked to the concept of "pet" and definitely not with the concept of "oven".

Problem is there are still kinks in the relationship between concepts part. AI is modeled on the human brain and the human brain is not a perfect system. In theory writing a simulation for the human Id, Ego, and Super- Ego and bundling it into a sentient AI package is quite doable. Making it happen while the foundations are still unstable is practically/near impossible.

There is a easy way to test for this. Set a magnet on your desk. Now, rotate it 180 degrees, and set it down again.

Does the magnet suddenly snap back to its original position, or otherwise slide over your desk in search of magnetic north? You are probably (correctly) thinking this is a ridiculous experiment. It's obvious that earth's magnetic field is not strong enough to do stuff like that.

So, if the earth's magnetic field is too weak to even move a unsecured magnet that probably only weighs a few grams, you're expecting it to affect a billion tons of rock in the form of continental plates?

You can even see a complete absence of effect ib the exact same rocks you are referencing. These rocks provide evidence of past pole reversals, because different layers have different alignments.

If the polarized rock moved into alignment when the fields shifted, new layers would always be deposited with the same alignment as the old ones. The only reason these rocks are even referenced in the same breath as pole realignments is because this doesn't happen, and cannot happen.

Finally, to see how magnetic the average rock is, obtain a compass, a magnet, and a piece of gravel. Gravel is made exclusively from the least valuable (e.g. Most common) form of rock readily available, so it is a good stand in for the average composition of the earth's crust.

Find the furthest distance you can that leads the compass to point towards the magnet, rather than magnetic north. If the compass is pointing at the magnet, this means it's feild is dominating over the earth's field at that distance. Replace the compass with gravel. Does the gravel slide towards the magnet at this distance? If not, this shows that the magnetic minerals in the rock are insufficient to move it, despite being in the presence of a local magnetic field strong enough to dominate over the earth's natural field (as shown by the compass)

We routinely experience magnetic fields thousands of times stronger than the earth's own, and nothing tends to happen. The same is true of most rocks.

Nope, some new ones empty themselves. Sure eventually you have to empty the larger container, but as long as they don't get lost they'll return to the charger, empty, and go back out again when needed. Pretty much fully automated.

Appliances aren't robots though. You don't call a regular vacuum a robot because it picks things up for you. You wouldn't call a washing machine a robot either. It's an appliance.

Now if we had a little rolly guy that would collect dishes, wash them (in a dishwasher + spot cleaning "by hand"), and put them away, THAT'S a robot.

Same for clothes. Assuming you have regular places for you clothes it could grab them from the dirty hamper, wash, fold, and put them away.

Honestly we could probably build a robot to do those things already, we have good enough tech. When it's the same items repeatedly rather than new stuff, pattern recognition is pretty great.

> most navigational systems use some version of GPS, which aligns through satellites rather than magnetic compass

Actually no, compass and GPS can't substitute for one another. GPS tells you your location, but not your orientation. If you are standing still, GPS won't tell you which direction you are facing (or which way the front of your vehicle is pointing), but a compass can.

If you are moving, GPS can tell you which direction you are moving, but on ships, airplanes and spacecraft, the direction you are moving is not necessarily the direction your vehicle is pointing. So you still need a compass. A gyroscope also works for this, but gyroscopes drift over time, so a magnetic compass is a more accurate long-term reference.

Spacecraft often use star trackers or sun sensors for determining the orientation (attitude), but some do use magnetic sensors. And also, most satellites rely on magnetic torquers to change their attitude. Reaction wheels (aka flywheels or gyroscopes) are also used, but they eventually saturate (moving as fast as they can) and eventually they need to offload the angular momentum to something external. That something is usually a magnetic torquer, which is an electromagnet that basically pushes against the Earth's magnetic field to rotate the spacecraft. Thrusters also work for this purpose, magnetic torquers are far simpler and cheaper, so most satellites in low orbit just has magnetic torquers, not thrusters.

Succinct and well stated.

I’ll add that there is clear alignment “striping” of magnetic particles on the ocean floor. So by drilling different parts of the sea floor one can see which direction north and south were when the magma that makes up the sea floor was deposited. Once it solidifies, however, no further change occurs.

A lot of people are saying this is the “real reason for climate change”

I don’t trust the corporations who are paying for scientists.

And I think it makes a lot of sense that the entire magnetic field of the earth changing would have an observable effect… like isn’t that how wind and weather and tides move?

I need ppl to explain this to me, because I don’t trust scientists funded by gas corporations. Sorry. Most “science” out there is incredibly biased because of money and money and money. Most studies only come out because the money it will make corporations. It’s so easy to buy science and I just don’t get how the literal magnetism of the earth ISNT causing a noticeable effect??? Maybe I don’t get magnetism.

>On average our experts predicted that 39 percent of the time spent on a domestic task will be automatable within ten years.

From the paper's abstract (Lehdonvirta etal 2023. As always, the headlines seem to capture it just right.

>Japanese male experts were notably pessimistic about the potentials of domestic automation, a result we interpret through gender disparities in the Japanese household. Our contributions are providing the first quantitative estimates concerning the future of unpaid work and demonstrating how such predictions are socially contingent, with implications to forecasting methodology.

This was the purpose of the paper, not the survey or the 39% number. It's to improve the methodology of these kinds of surveys and show that there is cultural bias in respondents that must be weighted.
