So give me some predictions as to the Meaning of it all. I've found this show generally defies predictions, cause it makes so little sense.
I'm predicting that the island and possibly the entire world is some kind of simulation/computer program run by the Smoke Monster and Jacob. This would be inline with the idea that if the smoke monster left the island, everyone on earth would cease to exist, along with the entire history of mankind. If Smoke Monster wins his bet that humans are destined to be corrupted, then he can assume that they have no free will and thus do not really exist, and end the program. If Jacob is right and humans do have free will and choices, this will prove that simulation or not, they really do exist, and the program will continue.
Of course I'm probably totally wrong and the ending will make just as little sense as the entire show.
