I knew these existed but I can count on one hand the number I've even clicked on. They're universally 99% bullshit because it's all just a persuasion speaking gig. Not an educational lecture by any means. Popularity rules, so they just stick to popular or provocative things.
If you hear someone say they learned about something in a TED talk, their depth on that subject cannot be great.
Read and find out for yourselves. It's all humanity has... otherwise it's just old caveman word of mouth.
