And they said five year plans struggled with predicting demand ;)

I'd rather go with "for any delta in mining convenience between solar systems, there exists a level of FTL magic where shipping would become economically feasible"

Perhaps space slow steaming might be an option if your goal was to make a Dyson sphere exist before the star inside burns out?

Hogwash! We can do it much faster than that. With a machine in Alpha Centauri capable of flinging rocks full of rare earth metals back towards the solar system at 1/10th the speed of light, we could be up and running in <150 years.

This feels about as realistic as most of the spacetech proposals I hear.
