You have left out basic curiosity. There are two not necessarily mutually
exclusive paths to transhumanity. One is inward into our self constructed VR
worlds, the other is outward into the universe. Some of us need to know what
is over the next hill, others prefer to create their own hills on canvas, or
watch hills on TV. Some who have the option to upload into a self contained,
VR world might choose not to do so, because they can't help but want to know
what is in the next star system in the 'real world'. I can forsee a future
in which the artists and couch potatoes of the world are all uploaded into
artificial worlds of their own or other's design, while the scientists and
explorers of the world continue to point their outputs towards the external
universe.
And the conservatives and idiots and religious fanatics, they'll still be at
their respective party conventions I imagine.
