Agree for your children to learn useless facts, but only those that have strategic value that will help keep the social peace within your immediate environment. Do you really need to memorize all the county seat names of your State or country? Probably not, but maybe your old great-grandpa Herman who lives with you is insistent that your children will grow up to be barbarians without a chance to make it in life unless they do. He’s not on the Internet, but he still remembers WWII and that back then they had to memorize that list in boot camp and that proves that it was that kind of toughness that saved civilization. You can waste time on that list, but only because it has strategic value to keep a critical peace – the rest of the stuff is SPAM and you must ruthlessly spend time cutting out the twaddle if your children are going to become great in their talent.
