Strange Baby

Suppose that a baby is born at the Institute for Evil Neuroscience. Well, maybe not a baby exactly -- a human baby brain, suspended in nutritive fluid, with a truncated respiratory, digestive, and circulatory system hooked up to an oxygen input tube and a feeder tube, with connections to the brain's punishment and reward center so that the right kinds of nutritive/homeostatic inputs trigger reward, while deprivation and drift from homeostasis trigger punishment. Additionally, this baby brain is supplemented with two novel appendages of neural tissue. It has one general-purpose appendage, with ten times as many neurons and neural connections as an ordinary human brain, divided into subareas of various sizes and various levels of connectivity to each other, and constituted by a variety of neurons in a variety of ratios, but with no pre-dedicated purpose of any sort. And it has one brain-sized direct interface with an ordinary desktop computer with a variety of software and with internet server functionality. These neural appendages are connected to, or grow out of, the corpus callosum, almost like cortical hemispheres. More or less, this is a four-hemisphered baby.

The first thing Strange Baby has to learn is to feed itself. It has a bank account of $10 million to start with. Scientists at the IEN nudge some of Strange Baby's early processing toward ordering nutrient packs from hospital supply centers, which at first they hook up to its feeder tube. Soon, they start to wean it from dependence on them by teaching it to pay independent home caretakers to do that work: the IEN scientists stimulate its reward centers when it does the kinds of things that give it increasing independence of them. At first they do so by explicitly giving fairly directive input, then they slowly reduce the structure of the input, letting Strange Baby's own reward center take over. Eventually, through their guidance, Strange Baby is paying not only for home caretakers but also for a custodian, for occasional building repairs, for power and air-conditioning, etc., as well as for direct maintenance on its computer (which it starts to expand and upgrade). Once the IEN scientists are confident Strange Baby can maintain homeostasis, they no longer regularly enter the building. At first, they visit occasionally to give Strange Baby medical checkups, but soon these too are contracted out.

Strange Baby's $10 million won't last forever, so she needs to learn to supplement her bank account. She has picked up linguistic patterns from internet usage, gaining differential reinforcement from chat groups: The IEN scientists set things up so that if Strange Baby can produce text strings that generate extended and diverse responses, she finds that rewarding. The IEN scientists had also kindly given Strange Baby an initial nudge toward Mturk, and gave it some initial input-output templates for starting Mturk accounts and accepting Mturk tasks. Through trial and error, Strange Baby found patterns among Mturk tasks that yielded bank account increases, generating neural reward.

Eventually, Strange Baby is a fully linguistic member of the internet community, motivated to maintain homeostasis, increase her bank account, and say things in chat rooms, blogs, and on other social networking sites that generate long and diverse responses.

Strange Baby can't see with her eyes, for she has no human eyes, though she can access public cameras and she can request camera input from friends. Nor can Strange Baby hear in the normal way, though she can access microphones and she can receive voice-protocol inputs and produce voice-protocol outputs. Eventually, Strange Baby convinces a friend to put a camera, microphone, speaker, and monitor display in her brain room so that she can directly observe her caretakers and contractors and communicate with them in modes they're comfortable with. She chooses a human face avatar that expresses her personality and self-image.

Strange Baby's sensory and cognitive experiences will share some features with our own, but she will also be very different. Her visual and auditory experience will, presumably, be multi-perspectival. She will be directly sensitive to internet slowdowns. And she will be sensitive either to input from her neural integrated silicon computer or to internet input (which of these will seem to her to be the sensory surface?) -- directly sensitive, no visual user interface required -- perhaps with special feelings associated with the balance of her bank accounts and the length and diversity of her various internet discussions. The computer/internet will, presumably, be by far her most important stream of sensory input. (We can call it "sensory", can't we?)

Strange Baby will have twelve times the neural capacity of an ordinary human being, with her dedicated computer/internet double-hemisphere, and with her trillion-neuron flexible reservoir which presumably gets shaped in ways useful to her goals. It seems reasonable to suppose that she will have conscious experiences of various sorts associated with these brain areas and brain functions. Such experiences will probably seem alien to us, like color to a blind person. Nor will the part of her brain that would be visual cortex in a normal human being necessarily be dedicated to visual processing, or auditory cortex to auditory processing.

Strange Baby will no doubt find even very complicated arithmetic easy; and presumably she will have a major advantage over the rest of us in more complex sorts of formal reasoning as well, since she will combine something like human neural capacities with computer capacities and with her own unique areas of neural tissue. I wonder, though: If she uses the computer's processors for arithmetic, will it seem to her that she is checking the computer like we do, but more directly and non-visually, or will it seem like the computer is part of her so that checking it is like using her own memory or reasoning? If the latter, Strange Baby might find even the most advanced human logicians and mathematicians painfully daft. Who knows in what other areas she might choose to excel, but it seems likely she could do very well in many areas, perhaps finding it easy to learn many different facts and intellectual skills.

She will want children.
