No, it just means that such kind of speculation is useless since the likelyhood of knowing your right is as likely as I'm right about speculating that the moon will turn purple tomorrow. We can all speculate, but it is useless unless we have something tangible to have any kind of validity in making those assertions.
Pure speculation is just that.
