Nobody knows when the world will end. It may end tommorow, next week or never. Everything is in a state of flux. This is nothing new, it has always been so. Just because the world, or specifically this planet is currently dominated by humans, there is nothing to say it won't soon be dominated by spiders. For you and me this would be uncomfortable and would definitely screw up our marketing plans. For the spiders, however, it would be business as usual.
