Ants/bees/multicellular cells are the best example of a working communist society, since they have dominated the entire world and have done so for over 100 million years. Ant society, although superficially monarchist, is actually communist. The queen is not a ruler, and rather is a worker for the greater good, producing babies. This is the sole reason why ants protect the queen. Not because of any hierarchy, but because the queen helps the workers, so they help her back. Ants have free education, free shelter, and free healthcare. Ants distribute all food to those who need it (for free), have co-operative broodcare, communicate the positions of food to other ants and are extremely altruistic. Not only this, but they are extremely intelligent for their size, being as intelligent as some primates. Ants can build cities, navigate in ways that humans cannot, use the sun as a compass, organize social events, distribute sap that is used as medicine, use larvae as tools, domesticate other animals and farm crops. It is arguable that ants could even be the true dominant civilization on this planet, as they have been around for far longer than humans, are on every continent apart from Antarctica, and they have survived every extinction event for the past 100 million years and came back stronger.

>The greater good
Are ants working for a greater good that includes other species? If no, then how is this any different from a nation state working for the benefit of it's people, or a corporation working for the benefit of its members, but disregarding outsiders? (which communists seem to oppose).
Restricting "the greater good" to just ants seems no different in principle to restricting "the greater good" to just Germans, or to just the members of a corporation.

Are any of you Persuing graduate degrees because you were failures in high school? You were unremarkable and no one ever took you seriously while all you're friends got better grades than you, and were in higher level math classes. You're trying to get a PhD in some STEM field so you can feel like you're better than those annoying gifted kids. I can't help but feel like this is a major motivation for me wanting a graduate degree. It sounds petty I know, but I'm sure some of you understand what I'm talking about.

Jesus did you attend Mensa College? You do understand how rare gifted people are right? I think it's like 1 in 10000 or something close to this. I think what you meant is academically talented xD

This is roughly how many people study pure math. Based of graduation statistics from Scientific American.

>5000 in 10000 never attend university (lower in most countries)
>3000 in 5000 of those attending tertiary education do a business degree
>Of the 2000 remaining only 500 do STEM
>400 in 500 of those do biology, psychology etc
>50 of the remaining 100 do computer science
>30 in 50 of those do chemistry, materials science etc.
>15 in 20 do some kind of engineering
>3 in the last 5 do physics
>1 in 2 of the remaining does applied math

Honestly, maybe if you spent more time writing papers instead of taking holidays to Japan you could've at least gotten a national lab position.

The real statistics is closer to 5%.

The Physics and Math majors who work as coders are just sad. What was even the point of taking on the hardest shit just to end up doing coding, and probably not very proficient at that?

You can call CS a meme but Math and Physics graduates who ended up as code monkeys the ones who got massively meme'd on.

Is Dialectical Materialism (formerly Historical Materialism) a science? Marxists claim it is because it is a materialist view instead of a subjectivist one. DiaMat posits three laws which matter abides by:

1) The law of the unity and conflict of opposites.

2) The law of the passage of quantitative
changes into qualitative changes.

3) The law of the negation of the negation.

Granted these are Engles laws, which were expanded on by Lenin and Mao. DiaMat to this day hasn't been successfully refuted by scientists, its mostly just ignored. Jay Gould did use DiaMat however in his theory of punctuated equilibrium. A summery of the materialist outlook of DM can be found in the image, written by Stalin, who considered himself a social scientist.

>which Chomsky ruined with anti-Marxism
Was actually interested but you completely lost me here. What's your argument other than "it's anti-marxist"? Because that just sounds lile dogmatic adherence to a philosophical outlook and Chomsky abaolutely revolutionized linguistics from the pathetic, stagnant state it was in before him
>>
>>10823440
Chomsky thinks that language was literally just a random mutation from a cosmic beam. And that social organization among apes had nothing to do with it. Also thinks that every single possible word somehow exists in everyone's brains and is pre-defined.
>>
>>10816535
>Has it ever been refuted?
Has it ever been validated?
I could make a compute shit out trillions of random conjectures, and unless they are validated to some extent, there is no reason anyone should waste their time refuting them, and attempting to convince them that they should (outside of providing some validation) would amount to nothing more than a stalling strategy.

Why can't people just leave things alone and let things sort itself out?

>According to a study published in the science journal Nature Communications, land-based vegetation has boosted its carbon dioxide absorption by 17 percent compared to 30 years ago. Even more astonishing, the study notes, these land plants are using less water to do so.

>In other words, as the planet's CO2 levels rise, plants are soaking up more of it — and doing it significantly more efficiently.

Just think of all the man hours wasted and economic damage trying to fix a problem (climate change) that would eventually fix itself.

Another example is the hysteria with Tasmanian Devils with transmissible cancer, all the man hours wasted on trying to prevent them going extinct and in the end some of them developed an immunity to the disease.

Damage that fucked up not only economies, but ecologies, especially in South America where the rising battery industry has destroyed life in entire climates.
