I like the Kahneman "Thinking, Fast and Slow" systems concept and I would extend the metaphor using CPU (slow) and GPU (fast). I would agree that the brain is inherently slow, using the CPU metaphor it has an embarrassingly low clock rate. But each tick is supported by brilliant hardware optimization (GPU) so the data throughput and processing per tick (and watt) is remarkable. So yes I agree it is slow, but then the art of a BCI will be interpreting the state changes between these slow ticks that actually represent tremendous amounts of data.
