Particularly concerning is the fact that they are not a not-for-profit entity, and it is hard to understand how they might make money.
Charles Simon, the founder, is pretty focused in how natural neurons work vs artificial neural network models. He has some good explanations of that, and one major focus of the project is their semi open source spiking neuron simulator BrainSimII. While Ciro Santilli believe sthat there might be insight in that, he also has doubts if certain modules of the brain wouldn't be more suitable coded direclty in regular programming languages with greater ease and performance.
FutureAI appears to be Charles' retirement for fun project, he is likely independenty wealthy. Well done.
