Agreed. I don't like that you're downvoted for pointing this out as the language is very weasel-wordy (revealed to have? by who? what is all of Facebook?):

> Zuck is also revealed to have given the Chinese state access to all of Facebook

Tbf, the book actually makes the right claim that it's Chinese user data, not all of Facebook so the article is to blame.

Seconded! Great read though maybe a bit reductive in places

Why are room temperature superconductors an 'obviously-impossible' technological claim?

Asking since we've managed to increase superconductor temperature several times in the past, right? (to ~ -130 degrees celsius right now IIRC). Why is our current temperature of, say ~30 degrees celsius special?

In the book "The Quest for Community" (1953), Robert Nisbet argues that social function is primary and natural and leads to true association which for man fulfils a core need. From the book:

> In a highly popular statement, we are told that the family has progressed from institution to companionship. But, as Ortega y Gasset has written, “people do not live together merely to be together. They live together to do something together”. To suppose that the present family, or any other group, can perpetually vitalize itself through some indwelling affectional tie, in the absence of concrete, perceived functions, is like supposing that the comradely ties of mutual aid which grow up incidentally in a military unit will along outlast a condition in which war is plainly and irrevocably banished . Applied to the family, the argument suggests that affection and personality cultivation can somehow exist in a social vacuum, unsupported by the determining goals and ideals of economic and political society.

Going on a tangent, my current beliefs are that:

1. Social functions (i.e accomplished through association) has always had, and will always have high marginal utility, independent of and utilising any technology.

2. That there are political and not technological barriers suppressing it in our current age.

3. That humans are evolved to interact with large numbers of humans (probably seasonality), and that our evolved sociality is scalable even to the present day and beyond (i.e a rejection of Dunbar's number as an evolved constraint)

A lot of comments mention John Ousterhout's book Philosophy of software design and it's definition of complexity of a system being cognitive load (I.e the number of disparate things one has to keep in mind when making a change). However IIRC from the book, complexity of a system = Cognitive load * Frequency of change.

The second component, frequency of change is equally important as when faced with tradeoffs, we can push high cognitive load to components edited less frequently (eg: lower down the stack) in exchange for lower cognitive load in the most frequently edited components.

Great book! IIRC, after attending the 2005 USA memory championships as a journalist, he became intrigued and started training and in one year became USA Memory champion in 2006 at age 24

I'd tried applying memory training lessons from this book a few years ago and written about my experience: http://web.archive.org/web/20210301185111/https://ppsreejith...
