Number 3 is slightly misleading. We’ve known for years that spidersilk is weight for weight stronger than steel, and certain species even Kevlar. But, the feasibility for farming spider silk from spiders is…less than favorable, because they produce small quantities. Some years ago, the same university did this with goats…and then with some kind of plant (the species escapes me). And now I guess they got good enough at it, to do it with silkworms, which naturally produce lots of silk. The process has been done before, but now it’s gotten closer to relevant amounts. #16 does not deserve to be on the list. It’s cool, but it did not “bring the internet everywhere”. We’ve had smartphones for a while.
