The problem of education

No.13433108 ViewReplyOriginalReport
I'm not sure if this is the right board to post this on and if it's not, let me know and I will delete the post myself. What is the points of grades, you either know perfectly the subject or you don't. What is the point of education if you can just know half of it, and then you will also continue pretending to learn even more advanced stuff even though you barely know the basics? Isn't this very anti-scientific and anti-productive to a civilized society?

>I've listened to Childish Gambino, so I know more about the African race than this RACIST doctor who spent his whole life around Africans does!

Embryo selection for IQ is already happening underground. I personally know an elite who recently paid for this process. Here is what will happen. Most people will succeed in banning embryo selection, elites will simply evade the bans, and after a few generations the IQ gap between elites and nonelites will be so significant that your chances of joining the elite world as a non-embryo-selected person will be literally zero. The power differential will be greater than any in history. All because people moronically pushed to ban embryo selection without realizing how easy it is to evade laws if you have money.
