It really does not make sense how we don't have spider-silk rope. Considering our level of technology, I could be it would be surely possible to manufacture some, it would be one of the most useful advancements yet.
If you either hate spiders or know not-so-much about them, the reason spider-silk rope should be made is because of it's tensile strength. It may not make sense, considering how easy it is for us to rip apart webs with barely any effort, but that is only because of how thin it is. The tensile strength of spider silk is actually tougher than steel and theoretically, a thread of spider silk as thick as a pencil has the ability to stop a jumbo jet straight in it's tracks.
So once again, I ask: Why don't we have spider-silk rope? It's obviously not possible to get them naturally (since we would need a spider over 10 feet long to make a thread that thick), but I'm fairly sure that we are advanced enough in technology to manufacture our own. It has a whole world of uses, most of them are probably military uses.
I hate using over-exploited memes, but....
SCIENTISTS, Y U NO MAEK SPIDER ROPE?
