Given the current rate of technological growth it won't be long before we have a choice to make. Do we move into our simulations or do we continue into outer space. Virtual technology doesn't seem all that impressive right now but how long until we can have a BCI that will allow us to experience virtual worlds like Avatar or ancient Rome indistinguishable from reality.
When we can create worlds and modify it any way we want will we still want to continue living in the real world? Is it possible the reason we can't find aliens is because they're all living in their simulations?
