It doesn't even matter what the SNR is. EEG is an extremely low bandwidth signal that measures average activity of BILLIONS of neurons. It's not possible to do anything significant with it. These guys are just capitalizing on hype and they will be able to build some toy demos, but never anything really useful.

As an anesthesiologist working with EEG to monitor anesthesia, thank you for this comment.

I wouldn't say you can't do anything significant, it's a bit like listening on a computer with a stethoscope. You can certainly deduce something from fans and psu noise etc, but it's VERY crude.

Neurons work in a coordinated manner. Experiments with monkeys shows you can get by with a lot of undersampling. But orders of magnitude still seems to matter.

I wouldn't discard the bandwidth of EEG so quickly. Clinical EEG has low bandwidth (<100 Hz), but in principle you can get up to the kHz range, enough to pick up individual neuron activity. Of course you will pick up mix of many neurons at any given electrode, but if you could ramp up the electrode density, it would make some degree of unmixing possible.
