> All pieces are there, we just need to decide to do it.

Another silver bullet.

I see a lot of parallels in Korean (and other eastern countries) and Indian social expectations.

While Korea has developed economically and has become a modern industrialized country all of it's social mores and expectations are rooted in it's feudal agricultural past.

I think that similar situation will happen in India as well in next 20 years.

Maybe Western modern industrialized, post-industrialized society needs a individualistic culture as well and does not harmonize well with society whose values are derived from the older feudal, gerontocratic agricultural society.

I have a feeling that Megalopolis is going to end up as one the great cult classics.

I would also recommend 1st chapter of "Principles Of Computer System Design: An Introduction - Saltzer & Kaashoek" for a more general discussion on complexity in digital system.

> Physics has repeatedly had to tame infinities by elaborate tricks, or by eliminating them entirely

or In case of black holes by actually interpreting infinity as a real place in the universe.

I wrote simple implementations (simple if/else/while and printing to stdout) with no optimizations in Rust, Python3 and C

Rust -> 23.2MiB/s

Python3 -> 28.6MiB/s

C -> 238MiB/s

Does anyone know why Rust's performance is in the same ballpark as Python3.

I thought it would be more closer to C.

If someone is interested I highly recommend Tech Yourself CS website, it is much more concise and complete set of resources.

One possible outcome of this is humans stop producing freely accessible digital artifacts like text, code lest they get replaced by machines who can mimic them and which controlled by tech moguls.

Lol, you are calling an act of rebellion a crime.

Now I am begining to understand why people like Moral Relativism, it gets them gotcha moments on internet.

> I’m wondering if someone can comment on the cultural aspect here. It seems like adding the smiles was intended to discredit the protesters, by somehow suggesting the protest was insincere.

This was to paint them as insincere and implying that protestors are on the payroll of <insert boogeyman here>.

I think the part about "unrealistic goals" is applicable to a lot of spheres of life and exacerbated by the social media. Social media after all inflicts high expectations and pressure to convert your life into a performance on everyone irrespective of profession, culture, age, country.

And ofcourse the Titans of social media - zuckerberg, chamath, tiktok and 1000s of engineers, PMs will not pay for the harm their engineered products have caused because waters have been muddied enough and no true accounting of the harm can happen.

It is kind of like inventing a new synthetic highly addictive drug which is technically legal but very harmful and you can sell it to everyone.

Should rich people get less jail time because they lose more money because of time spent in jail (per day income is higher) than a poor person.

Should a person with more children get less jail time because more children will be left without a parent as compared to a childless person.

> but to me it seems like a good idea to at least consider the potential negative effects self-expression may have on others, and weight that against the benefits of self-expression.

There is no end to self censorship.
