Software is eating the world -- the economy is dematerializing.
What are the physical effects on living human beings?
🧵

The effect is that every year we spend marginally more of our waking time inert, staring at screens. Often in chairs, spines collapsed; or slouched on sofas, cpus heating our gonads.

No muscles of our exquisitely evolved bodies in motion except certain small muscles of wrists and fingers.

Our eyes, also, inert: perpetually focused on banks of LEDs flickering 60 times a second. Fooled into a perception of distance which lacks the proprioceptive feedback of eye movement.

For neither the tiny muscles of our eye lenses, nor the muscles that move our eyes in parallax to focus near and far are engaged.
