Neat concept! Although I was a bit surprised at the AI stand-in's finding. I posed the silly argument that "My neighbor's dog refuses to speak French" with the options "Neighbor is culpable" and "I am clearly an idiot": The final decision was 7/5 in my favor! But seriously, this really is a great idea IMO. The jury-duty-while-you-wait feature also seems like a fair trade-off.

But is it, really?
That was already the era of "information overload" and "future shock."
Relatively speaking, perhaps, but things really have progressed by several orders of magnitude. When I was young we had access to very little "technology". (Maybe that's why people tended to be somewhat more down-to-earth?) I could change a tire by the age of ten, not to mention being fairly well-versed in a number of subjects. And I was certainly not the exception. Any given person was bound to be proficient at *something*. Younger folks these days however (on average) don't seem to think very deeply about things (probably too many distractions?) and as a result they can be surprisingly ignorant across the spectrum. Not all of them, of course, just an alarmingly high percentage....
This has literally nothing to do with the article for this post.
Of course it does. The National Post article I linked to is about Mahmoud Khalil, who is indeed mentioned in the Zeteo article.

Compared to most websites these days HN is about as lightweight as it gets. I would say if you are experiencing laggy page loads, the issue is most likely something else. (Maybe disable extensions and restart?)
> The prime-counting function approximation tells us there are Li(x) primes less than x, which works out[5] to one prime every 354 odd integers of 1024 bits.
Rule of thumb: Want a 1024-bit prime? Try 1024 1024-bit candidates and you'll probably find one. Want a 4096-bit prime? Try 4096 4096-bit candidates and you'll probably find one.
The approximate spacing of primes around p is ln(p), so ln(2^1024) = 1024*ln(2), and ln(2)=0.693 so if you are willing to absorb 0.693 into your rule of thumb as a safety margin you get the delightfully simple rule of thumb above. Of course, you'll still want to use a sieve to quickly reject numbers divisible by 2, 3, 5, 7, etc, and this easily rejects 90% of numbers, and then do a Fermat primality test on the remainders (which if you squint is sort of like "try RSA, see if it works"), and then do Miller-Rabin test to really smash down the probability that your candidate isn't prime. The probabilities can be made absurdly small, but it still feels a bit scandalous that the whole thing is probabilistic.
EDIT: updated rule of thumb to reflect random candidate choice rather than sequential candidate choice.
Iterating over some huge search space in an essentially sequential manner is generally not going to be nearly performant as simply selecting an odd number at random. You could try using a generating polynomial instead such as f(x) = x^2 + x + 41 but even that isn't going to help much in the long run. (There are Diophantine equations which one day may prove useful for generating random primes however AFAICT finding efficient solutions is still currently considered a hard problem.)

Wealth inequality causes social disorder. All those other non American cities exist in places with more robust social safety nets and have fewer billionaires/less overt corporate control of the government. This is a fundamental truth of human society.
Blame it on bad culture. Good people know that orderly conduct is necessary to maintain a healthy and vibrant community. Just take a look at the Nordic countries where this used to be the absolute norm across the board. Now even there you see quite a bit of social turmoil. Many who have migrated to these countries over the years simply do not share the same values and the effects are sadly self-evident. People do not feel nearly as safe as they once did. It may not be as bad as the average American city, mind you, but there has nonetheless been a real change in the "atmosphere". (Which isn't to say "all migrants are bad". Unvetted immigration is the issue I am referring to here.) Point is, wealth-inequality has nothing to do with it.
Also interesting to note that not only has Berulis' attorney lead multiple lawsuits against the Trump administration in the past, he was also an intern for both Chuck Schumer and Hillary Clinton. Now that obviously doesn't prove anything, but it could nonetheless be considered a strong indicator this all might be politically-motivated.
