Aeon: What if ET is an AI?

Aeon: What if ET is an AI? 

If this pattern of machine development is happening for us, it could represent a pattern that happens across the cosmos to influence the nature of cosmic exploration itself. Savant AIs would become the ultimate tools for allowing biological life to reach across interstellar distances: more robust than biology, and not smart enough to raise ethical concerns about being sent off to roam the cosmos according to our scientific whims. Propelling millions of these investigators into space would be an inevitable step. They could be sent to other stars and planetary systems, and designed to recognise the most interesting characteristics of these places, from astrophysics to the presence of life. These machines would reflect the motivations of their biological creators; perhaps simple curiosity, perhaps something more.
Another compelling reason for savant machines to be roaming the cosmos arises from thinking about how to build more general, more powerful AIs. It might be that a general AI system can be built out of lots of smaller savant AIs, each taking on some specific, difficult cognitive task, but linked together. That linkage could be very localised or quite spread out like the architecture of biological neural circuits. There’s the face-recognising savant, the natural-language savant, the calculus-savant, the tax-evading savant. One could then imagine an AI whose job is to learn how to combine savant AIs into something akin to a general intelligence – establishing a nursery for machine consciousness run from on-high.

The most challenging task for a nursery-room AI would be how to expose its collective of savants to the complexity of the real-world environment. Nature isn’t just about meeting fixed goals; it’s full of noise, randomness and trillions upon trillions of interacting pieces. For example, from the very instant an embryo forms, it is exposed to constant variation. First just a few cells, it senses the world purely from a molecular point of view. As the embryo develops organs to register light, sound, touch and smell, the portals to experience – and their complexity – expand.

In short, the way for a species to make a better AI is to let that AI and its components explore the messy Universe. As complex and nourishing as a single planet can be, a cosmos filled with worlds offers millions, billions, even trillions of natural test tubes, each with its own tale of natural selection and chance. Spreading savant AI pieces across the stars offers a way to exploit these endless natural experiments and sensory inputs.
