Fictional technologies ranked by real-world payoff

Which technologies from Glynn Stewart's science-fiction settings would be most valuable in reality?

The choices include asteroid mining and industry in space, medical technology, brain-computer interfaces, implants, power armour, marine enhancements, and the Castle Federation's matter fabricators.

Asteroid mining is chosen for its potential to change Earth's economy by opening access to off-world resources. Combining extraction with an industrial base in space would extend that change. Medical technology and brain-computer interfaces are other preferred imports from Glynn Stewart's settings. Power armour, marine enhancements, and smaller implants also appeal to individual members of the panel. The Castle Federation's matter fabricators are singled out for their usefulness across engineering work.
