What has happened to this site? We have a topic on the front page of the site for 15 hours now, with almost 400 comments, and the top comment is a nakedly eugenicist screed about "the dumbest people" having too many babies.
I mean, even skipping the moral horror here, it's not even true: https://en.wikipedia.org/wiki/Flynn_effect
But HN... wants it to be true? What the actual fuck, people?
ive been here since 2014. i didnt bring up eugenics, but if you want to broach that topic then fine. intelligence, as well as all other traits or characteristics, of not just humans but all organisms, is subject to natural selection. if you deny this, you deny natural selection and this would make you a science denier. whether we should act on this fact, or the morality of doing so, is completely up to you. but you will not deny science on hackernews.
oh and you saw my comment at the top because the ranking algorithm takes the youthfulness of the comment into account. its rather embarrassing that you dont know this.
very frequent topic here on HN. i remember a comment about a persons experience with the public schools in the soviet union when it collapsed. all the smart people pulled their kids out and did something else. its the same as everything else because if you want it to be done right then you have to do it yourself. there is no fixing public schools... they are run by the majority and they always will be. the problem isnt the schools, its the majority. after WW2 all the dumbest people fucked like rabbits with no financial or existential limitations to stop them, medicine increasingly spared idiots from the consequences of their actions. this initial seed of stupidity brought the next tooth of the ratchet into place: the popularization and normalization of eliminating all consequences from ones own actions. we just keep getting dumber. we were supposed to be re-galvanized by a major depression and a pandemic in the past 20 years but we postponed it all with technology and massive economic manipulation. eventually the chickens are going to come home to roost... in the meantime dont let the public schools rot out the inside of your kids head.
i love the time that we live in. people talk about there being a glut of podcasts, but i can type "Peter Scholze" into youtube and there is a full hour-long interview with him hosted by another mathematician. you can see her channel is very new and almost certainly a part of this latest wave of pandemic podcasters. its so great to take an interest in a random person from a nature article and be able to immediately get a visceral idea of who he is and what hes about.

.
yes, exactly. everyone is very quick to point out how evil the united states is. but there is no public reaction about the soviet union in which millions upon millions of people were deliberately murdered. more people than the nazis and the united states. i point out the absence of objectivity when i see it because i am a good citizen.

its strange how soviet union stuff is a fetish for coastal people but you never see much nazi stuff. the soviets murdered more people than the nazis and they are objectively evil. but that detail is simply lost somehow.

thats going to be one of the biggest shocks to society going forward when it comes to the changes that AI bring. there are mountains of data everywhere that is completely overlooked simply because the cost of processing the data is too high. too high to discover patterns/correlation and too high to process in any case.
human beings filter out most of what goes on around them. they dont see the world as it is and their minds dont keep track of physical primitives. their minds abstract the world into larger conceptual parts and track those parts. its not just a question of processing power, its a question of intuitive access. and nobody realizes this yet because the only sentient beings who are around to demonstrate any of this have those filters in place. when the AI comes with all that horse power and with no filters, it will see things all around that we are blind to. it will seem as though it can make impossible predictions. it will seem god-like, even before it graduates to doing something other than simply observing the world.
when the bike is making a correction, it can overshoot and then stop the wheel suddenly, which would ultimately result in the bike becoming perfectly upright and the wheel not accumulating any speed from one correction to the next.
if the momentum of the correction you need to make is greater than the momentum of the wheel spinning at max RPM, then the bike will fall over. this means that the system will fail if the bike is pushed too hard, becomes too off-balance or if there is something heavy, like a person, on top of it. with a wheel that was heavy enough, and a motor strong enough, the bike would be able to make itself upright from laying on the ground or keep itself upright with a person and cargo on top.
