Towards neurotechnology

There is a dragon outside our door and we only know to interact with it with chopsticks

To begin, take care that you locate the human in his place. His medium is air. He is bathed in electromagnetic waves, pressure, chemicals. He can sense a small range of a few signals and respond by the contraction and extension of fibrous cells on his body.

His sensors and effectors interact with the environment; his cognition interacts with the subenvironment of their neural impulses. His cognition is a volume circumscribed by his sensors and effectors.

You'll notice that his sensors and effectors are biologically plausible. He generates forces on the order of 2 to 7 g/mm^2, and cannot exert forces or detect changes on time scales lower than a couple milliseconds. Naturally, his cognition operates within this space.

They coevolved to be useful for survival.

The world surface has changed. Light, for which he has dedicated 40% of his brain, is no longer the primary house of information: everywhere around you, information is flowing in the modulation of currents.

Have accepted these design constraints: moving, adaptable circuitry

His effectors are individually addressable, but more often are packaged into behaviors.

His sensors and effectors circumscribe a volume which is his cognition. You are a brain, sensors, and effectors. Sensors transduce the environment: EM waves, pressure, chemicals. Your main effector is the contraction and relaxation of fibrous cells. The brain is the volume

The sensors and effectors are constrained by what was biologically plausible and useful for survival.

These were built as interfaces to world, and adapted to be the same interfaces to people.
