Human technology is beginning to border upon some fantasy level stuff. Gravity propulsion is now theoretically possible and equally capable of trans-light speeds. It also solves one of the greatest problems of interstellar travel. The human body rapidly deteriorates outside of our gravity. The solution, create onboard gravity.
Controlled nuclear fusion power is a reality. In its infancy to be sure, but the proof of concept has been achieved.
Transparent aluminum is no longer a Star Trek prop it exists.
Kinda glad I won't be around to see these technologies mature. Man as a species hasn't matured beyond its inherent self-destructive nature.
