I personally think all of the above! Technologically we could evolve our understanding of the greater sciences and secrets of the universe from the macrocosm to the microcosm.
The key point is the technology will only evolve as long as we do and if we accept that we can only or maybe last as long as our D.N.A pool will allow, or more importantly our own Sun then at some point in the future we would eventually have to face the ultimate truth, that if we want to still live we had better become masters of universe so to speak.
So space travel and deep space probing for habitual areas that have enough recourse to sustain life would now be a priority, think about it?
Compare the rate at which we are technologically evolving now to say in another one billion years time, its just mind boggling and in another approx two billions years after that the Suns temperature would have increased so much that it would be probably impossible to survive on mother Earth.
Think where we are now and try to imagine where we would be given those time scales, Stargates and space travel would be just normal or even maybe out dated who knows?
