Looks like they have ‘neuron culture and interface as a service’ going on, for all the good its for. Its a real thing. You grow some neurons and stick some electrodes into it, and you can measure the activity of neurons or groups of neurons through some electrodes and induce some to fire through other electrodes. Now, if you have some external process that you define that takes the output from the electrodes and does some computation on it and returns signals to the input electrodes, the way that neurons work and change their synaptic weights over time ensures that the network will learn to produce outputs that make the inputs more predictable. Hence teaching a few thousand neurons to play ‘doom’ - you have a program that takes the screen and turns it into a set of input strengths, take some outputs and turn them into controls, and it feeds back, and you eventually have something that learns to do predictable actions. Their innovation appears to be having standardized software you can use to define the input and output electrodes with respect to whatever other software you are running connected to the stuff. Who is willing to pay for this is anyone’s guess.
