If man can evolve some kind of overmind, which will satisfy all of his desires in a virtual mental space..?

If man can evolve some kind of overmind, which will satisfy all of his desires, in a virtual mental space, does he still need god? For example, if a man wishes to eat something sweet, immediately his overmind produces a real sensation of drinking nectar. If he wishes to have some sensual pleasures, the overminnd will put him into a transe and make it really happen in a virtual world. Anything and everything bolis down to electromagnetic sensations anyways. If such a thing happens, do we still need god in our life?
