Technology extends senses.

My sense of tiredness grows as my fingers move across the screen.

Dominant technology, dominant metaphors.

The talking heads of today call the mind a complicated machine; in other times, they spoke of its similitude with an unseen divinity.

Technology and psychology.

Ishi, “last of the Yahi,” laughed when he saw an airplane and heard a white man flew it. He seemed more impressed with the urban crowds made possible by the settler’s agricultural technologies.

“Neutral in itself, technology is only what we make of it.”

To see the limits of this perspective, remember a world without electricity or imagine a world where everyone is a tool.

We can move freely through time.

But we don’t need “high technology” and fancy machines to do it.

A journey to the stars.

The twin paradox captures the pathos of technology.
