You are posting on a US website. If you cannot handle comparisons to the USA, go find a European website. I'm sure they exist.

37C is 98.6 F ...body temperature. A hot day, but not out of the normal range for most of the USA in the summer.

It is horribly inefficient to do this, but it is a good experiment to learn from.

a human-shaped robot with a screen for a face recently stepped from a charging station toward a stack of green plastic boxes. It grasped an auto part from one of the boxes, pivoted, placed the part in a trolley, then pulled the trolley across the floor.

A conveyor belt would be far more efficient at this task. A sorting armature to pick the parts and place them on the belt. Another at the far end to place the part in position. None of this needs a humanoid bot slowly shuffling across the floor one part at a time.

Actual manufacturing plants need to make efficient choices in order to be profitable. They are not the place for these kind of experiments.

Two thoughts:

"Equivalence class" is like saying "A students, B students, C students, etc." You can certainly group people into approximate groups based on how well they fit the objective criteria.

I cannot support the idea of hiring randomly from the top group. Choosing "a good match for the team" is important -and it is subjective. Yes, people tend to prefer people like themselves. Yes, that can lead to discrimination. But hiring an asshole can kill productivity in any team. That is why we do interviews with co-workers: to get the feedback on who matches or does not, with management overwatch to ensure we don't just pick our bro's.

We are way off topic here, but... :)

The NBA -is- racist against white players. Watch interviews with players talking about Larry Bird. They say directly that their reaction to him was "Man, I ain't gonna play with this white boy", and then he smoked them on the court. There are dozens of star players who will say openly that they thought he did not deserve a place because he was white. He had to prove he was not only as good as they were but was better than they were, in order to earn respect from black players.

Freshman calculus kicked my ass -I got a D and had to retake it. I breezed thru calculus senior year in high school.

Lesson learned first semester: College courses move faster, and the professor does not explain everything you need to know. Studying takes more than skimming the book. Welcome to college.

Also survey courses were insane: Psych 101 was a lecture in an amphitheater with hundreds of students, one teacher, and a handful of TAs wandering around helping the helpless. The professor was on live video screens suspended from the ceiling around the room (like at a concert) so you could sort of see even from the nosebleed seats. Sink or swim, welcome to college.

Every empire rises, declines, and eventually falls into ignominy.

The USA has been in ascendance for the past century. We are now early in the period of decline. Likely still the most powerful nation in many ways, but clearly losing ground in many more.

The lesson is that the boss is always the boss: even when they are wrong it is still their decision what the right answer is. Good to learn it in school.

Grades are useful, but I still think any coursework outside of your major/minor should be pass/fail. Non-core courses can drastically effect who you are and how you view the world... it is important that you took them and that you achieved a minimum level of understanding/competency, but it is not relevant to your studies.

Your GPA even in the courses of your major doesn't mean much. It helps rank you among your graduating class -which may be useful in finding your first job. After that... not so much.

-Psychoactive drugs are effective at changing minds. The exact effects vary from user to user, but can be largely controlled by the clinician/therapist/shamanic guide. Taken alone or in random circumstances they lead to more random (sometimes bad) results.

-Psychoactive drugs are safe. They will not kill you. They will not cause physical harm. In a controlled clinical situation, the chances of a "bad trip" (emotional harm) are very slim.

-Psychoactive drugs are not broadly accessible only because we choose to limit access to them.

-Psychoactive drugs are cheap. They can be produced in laboratories cheaply and cleanly and in controlled dosages.

The first point is the one that is being studied currently: How effective are they? What are the limits of the effects? How long do the effects last?

I cannot say that I would be comfortable with psychoactive drugs as a first line of treatment. I am not in favor of drugs of any sort as a first line of treatment. If not needed, don't prescribe them. But I would not hold them out as a last resort either. If it will help someone, it should be an option.

Ceuta is a small island off the coast of Africa. It is Spanish territory -but no where near Spain. There are no troops, there is barely a police force on the island.

The invasion consisted of thousands of people going for a short swim... and then going back home in a day or two when they realized that they weren't going to be taken to Spain and given Spanish/EU citizenship. They voluntarily walked back across the bridge to Morocco.

Beware the Pax Americana.

Under the Pax Romanus, Roman citizens could walk the world with impunity, knowing that the simple statement "Civis Romanus sum! " (I am a Roman citizen) protected them from harm. Harming a Roman citizen would bring the wrath of the legions of Rome down upon the entire village where the crime was committed.

The US military is the largest in the world -and Trump is very willing to use it at the faintest imaginary provocation. Using the military in retaliation for a move against American citizens would be the most popular thing he could do.

Thanks to the Unitary Executive power now enshrined by our Supreme Court, then next president will be able to eliminate every Trumpist and replace them with their own loyalists. They won't even get a chance to fight it in court, as the lower courts will be bound by Supreme Court precedent. They may be allowed to retire quietly or there may even be mass prosecutions -depending on how extreme the next leader is.

If the Democrats control Congress as well, they will be able to reshape the Supreme Court, the Federal courts as a whole, and to set new legislation to prevent future leaders from repeating the cycle. The Unitary Executive power will be dismantled (after being used...) and the Supreme Court will be expanded and term limited to prevent such control from re-emerging.

The next elections will set the path. Will it be AOC's path? Pete Buttigieg's path? Or Gavin Newsom's path? Or will we re-elect king Trump for good?

It's bad enough we have government spooks doing this stuff, but now we are going to have private corporations doing it with even less oversight. Why not? I hear all the best countries do it this way...

What could possibly go wrong?
