because CAN is way more safe , the collision avoidance is built into the controller and is less noise sensitive
Just because the collision avoidance is done in the controller doesn't make it more safe. It only makes it better suited for hard real time applications, because the highest priority devices have guaranteed access to the bus. The price you pay is annoyingly short packets. If your software is good, RS-485 is just as safe, a bit less real-time, but more flexible.
The high impedance during the recessive bit makes CAN more noise sensitive.
We'll just sit on our asses on this one ball of rock until we use up all it's resources, poison it to the point where we can't even exist on it anymore, then our entire species will just die
Finding a second ball of rock where we can repeat this procedure isn't really helpful.
after that it's just trial and error loop so remind me again how is this ai?
It's not just trial and error. The Rubik's cube has 10 to the power of 19 combinations, and most of them look like fully scrambled cubes. You cannot randomly try things until you stumble on the solution. The AI part is where it learns the patterns that tell it that it's making progress. Most humans who have come up with a solution to the Rubik's cube start by first solving one side, and then the second layer, and then the top. This AI system has done something similar, except it doesn't work in layers, but came up with its own intermediate stages.
Plenty of differences, for sure, but look at modern apes, and you'll see male aggression and risk taking, and female nurturing.
It makes sense from a biological evolutionary perspective. A female has to carry the baby to term, at a great personal investment, therefore the female is very selective in picking the right male to have sex with. This leads to a high risk/high reward situation for the males, competing for the same females.
The summary and article are quite confusing. They started with solved cubes, and scrambled them in different amounts to generate training data so they could train a neural net to give the most likely candidate turns that would solve the cube.
After the network is trained, you can give it a random scrambled cube, and it will do a Monte-Carlo tree search based on the guidance of the neural net.
Games are easy for "AI" because games have strict rules
Just because the rules are strict (or even simple) does not mean that the game is easy. You can achieve arbitrary complexity by iterating the rules a large number of times. For example, the rules of Go are strict, the question whether a given board position is winning for white is hard. The rules of a programming language are strict. Writing a Linux kernel is hard. The rules of math are strict. Providing a proof for Fermat's last theorem is hard. The rules of physics and soccer are strict. Making a robot that can beat a human at the game is hard.
Anyway, if we're gonna run nuke plants I want them run without a profit motive. Otherwise there's too much incentive to cut corners on safety.
One does not follow the other. You can have a non-profit, but you still need contractors to do the actual work. And the contractors are naturally included to cut corners to make a bigger buck.
And if we're gonna have the gov't run every aspect to prevent that from happen then what's the bloody point of letting private companies run them?
Nobody in a government position has the expertise to run a nuclear reactor. They always end up hiring people to do the actual job for them. And every time a new government is elected, there's a chance that the work will be moved to a different group. Just look at other projects that the government has managed, and see how successful they were.
when sending cops to somebody's home counts as attempted murder? Britain and Canada don't have this problem,
Everything works in a context. With the realization that the US cops are trigger happy (partly justified because a lot more suspects are armed and dangerous), a swatting call has a decent chance to turn violent. Obviously, a similar attempt in Britain or Canada would be judged in the context of their society.
The font file consists of 2 parts. One is a mathematical description of the curves (typically using quadratic or cubic splines), and the other is a piece of program that helps to map the curves to raster pixel coordinates ("hinting") so that the fonts look nice on low resolution screens. Only the hinting program is subject to copyright.
For some applications (high resolution and/or advanced rasterizers) you could even leave out the hinting program.
Ancient languages hold the culture, heritage and wisdom of the people
And how many people are still alive that care about that particular culture, and would actually take the trouble to go listen to the restored recordings and understand what's being said ?
Looks like it's mostly a hobby project for people who aren't even part of that culture.
A large portion of the people that make ICE cars also make electric cars.
You assume that an electric car is similar enough to an ICE car that current car manufacturers can jump right in. However, the major manufacturing issue is the battery pack, and current ICE car manufacturers have no experience with that. Also, the vehicle control is much different with electric motors, and Tesla is gaining a lot of experience with that.
As far as natural gas, I don't think that would fly. Large parts of Europe depend on Russia for natural gas, and they wouldn't feel comfortable increasing that dependency. And if they can't sell them in Europe, it's not very interesting for car manufacturers. They don't want to make totally different cars for different markets.
From your link: Due to its low specific energy, poor charge retention, and high cost of manufacture, other types of rechargeable batteries have displaced the nickel–iron battery in most applications.

Indeed, why not use a simple open protocol on top of a physical RS-485 interface. Cheap and versatile.
It'll cost $8 to complete it.
Plus another $8 billion for unexpected cost overruns.
Spirit and Opportunity took 8 years to cover the distance the Apollo astronauts covered in 3 days
It would take more than 8 years, and a lot more than a couple billion $$$, to get astronauts on Mars, so the robots still win.
good luck studying the effects of space travel on humans just using robots
If we don't send humans to space, we don't have to know the effects.
An ecosphere is a more delicately balanced thing than you apparently think it is.
So how are we going to set one up on another rock that doesn't have liquid water and an atmosphere ?
We'll just sit on our asses on this one ball of rock until we use up all it's resources, poison it to the point where we can't even exist on it anymore, then our entire species will just die

but the vast majority of computer scientists I've met are atheist
Interesting. Yet another thing that needs to be fixed.
Everything was clear and described in simple, clear statements from the start. That is not how a real-world problem presents itself.
That's exactly how the problem is described on the box when you buy a Rubik's cube.
If you can make the plane 5% lighter with twice the assembly time, they go for it.
In order to make the optimal choice, you have to know in advance how much assembly time is required for each of the various options.
The summary and article are quite confusing. They started with solved cubes, and scrambled them in different amounts to generate training data so they could train a neural net to give the most likely candidate turns that would solve the cube.
After the network is trained, you can give it a random scrambled cube, and it will do a Monte-Carlo tree search based on the guidance of the neural net.
The number of possible cube configurations is too large to make a lookup table practical.

While Ikea furniture is designed with assembly in mind other things are not. Say for example, an airplane.
I would assume that an airplane designer is considering assembly (and maintenance, which is even harder) in every part of the design.
Second less than 60 deaths can be attributed to Chernobyl.
It also left us with a 1000 square mile exclusion zone.

while no linguist has ever completely and accurately described the grammar of any language. Which is very odd, when you think of it.
Not really. Most things in nature cannot be described completely and accurately.
Well get rid of the carpenter ants, anyway.
Or ask them to make you a bookshelf, or something. Try to keep them busy with useful stuff instead of eating trees.
