Anyone interested in how much your brain can do in a second? I'm making a mindmap/chart for that in my quest to better understand natural intelligence and how i

  The brain is always a fun comparison. It's this crazy super-scalar architecture that can do thousands of trillions of primitive operations per second (petaflops), yet with pretty terrible latencies: propagation through synapses on the order of single digit milliseconds, individual neurons only fire order of 1 time per second, input processing latencies in the hundreds of milliseconds, and primitive "logical" algorithms like "how many numbers can you count in a second?" netting out to "less than 10". So we end up in this state where what the brain does well computers are still (comparatively) terrible at, and what computers do well the brain is (comparatively) terrible at. We're slowly bridging that divide, with e.g. TPUs focussing on larger volumes of low precision operations happening in parallel, but we've got a long way to go yet.
