So hear me out...
Me and my friends were talking about how in the future spiders would be as big as horses because of genetic mutation. So then we said what if we learned how to ride them. And then we can train them. They could be set up with car bodies on top for people to sit in. Spiders can crawl up any surface which means you could go crazy places. And the webs they spin. Giant hammocks over canyons. I think spiders are scary as fuck but the possibilities with them are crazy.
