Well... i agree that the notion of an "ego" is both the bless and the curse of the human beings... the notion that there is one "me" that is separed from the "outside world" probably is what make us so different of the animals, but also is what makes us more sutpid than them. This notion make us more inclined to defend ourselves, to keep food for ourselves, to search shelter for ourselves, and so... or course, it is a very biological advantage, and it allowed us to survive, make societies, and arrive in the point we arrived today.
BUT, it has its drawbacks. The our "ego" is a (very small) part of the world, not the world itself. Most people lives for their egos, most people are slaves of their egos. They think their egos are the most important thing in the world, and dont understant that they are just a very small part of the world. They forget everything in the world is inter-related, and that what is causing the problems we live today, like destrucition of the environment, ambiental catastrophes, hunger, wars, and so... And im sure the cult of the ego is what will make the human race to destroy itself in the (not so far) future.
Only the plants and cockroaches will survive... as they are older, wiser, and egoless...
(And, of course they are wiser... cannabis is a plant! :stoned
