Good point about Stargate. I never really watched the show so I never thought of that.
They could have advanced every branch of science by hundreds of years.
But I guess their argument would be the humanity isn't ready for such technology.
It would have been a good storyline to follow. For example, how would teleportation technology affect the airline and shipping industry? How would the introduction of new power sources impact the oil and natural gas industry? I think there should have been some more attention focused on these issues.
