I think technology certainly is a key to a more 'Utopian' (desirable) society. The underlying problem is how we leverage the technology.

If technology is simply used to displace and concentrate wealth and power through private ownership without adequately sharing the benefits of growth in technology with everyone (reduced labor, more free time to pursue personal goals, etc.) then yes, it absolutely isn't helping (basically the situation we have now).

Can a Star Trek like economy ever exist? I'd love to be apart of one, but it seems unlikely given many underlying human behaviors.
