Hi. Welcome to my personal blog on lesswrong. I like youtube videos. I've posted lists of them before. Since then, more youtube videos have been made that I want to share, and tools for summarizing videos have come out! So I've wanted to share them here. To allow this to be evergreen where videos can be downvoted, I'll put the videos in comments with summaries. I'll use unvoting and downvoting my own comments to change the order, and others are free to downvote videos they don't think are particularly insightful as well.
If they really want to moderators are allowed to put this on the official frontpage tag but I think it'd be a little silly, as I'm not going to think too hard about exactly which videos to tell a particular story, and just share the ones I think would be cool to have shared. some of them might have bad epistemics, even!
Survival of the fittest does not preclude altruism in nature. Simulations show that unconditionally sacrificing offspring for others does not work in the long run. For altruism to evolve, there must be some benefit to copies of the altruistic gene. Kin selection, where creatures help family members who likely share the same genes, can allow altruistic genes to spread through a population if the benefit of helping outweighs the cost. While the genes are selfish in seeking to replicate, the altruistic behavior of the creatures themselves is genuine.
