Technological decrease

I need help in the following sentence. I am confused that what would be the right word for technological decrease in the following senetence:

Harvey says that modernity is the technological decrease of temporal or spatial distances of human conditions.

Según yo '''Harvey dice que la modernidad es la _______ de las distancias temporales y fisicos de la condicion humana''

Gracias!!!

I'd say "reducción tecnológica."
