I agree with you to a certain point that she is a prophet, but I think she's hinting at a much darker future than the one you percieved.
*"Starships were meant to fly"
This implies that in the future, people have decreased greatly in knowledge, rendered incapable of even figuring out that something called a "Starship" was designed for flight.
*Hands up and touch the sky
This could parallel the constant degredation of the ozone layer, which could become so polluted that we could get the effect of touching it just by raising our hands.
This could also mean that humanity has shifted back into the caves from which we came, where indeed the roof of the cave becomes the sky, and at some points we can touch it.
*Can't stop 'cause we're so high
Everyone in the future is incapable of recognizing their grim situation, as they are all addicted to some sort of drug.
*Let's do this one more time
This one's easy; "Shape it up, don't let this happen"
