Unconventional AI CEO Naveen Rao on expanding the boundaries of modern computing to account for biological efficiencies: "There's actually some theoretical results from the sixties, that would suggest we are maybe somewhere between seven to ten orders of magnitude away from the actual physics of computing. So we think three orders of magnitude is something we can accomplish in the next few years." "After that, we're going to have to rethink the actual fundamental substrate. Like, can we do this with electronics and silicon? I'm not sure. But what we're doing will open the door to new substrates, new kind of physical manifestations of computing." "If you think about it, human brains are twenty watts. If I sum up eight billion people times twenty watts, that's 160 gigawatts. The U.S. has alone about 1,000 gigawatts of capacity, and the world is about 9,000 gigawatts." "So we have a lot of energy in the world. We just have to use it more effectively and just think about what we can do if we can harness that for intelligence in a synthetic world." @NaveenGRao on @ThisWeeknAI(a16z)
