Machines generate waste heat when they do work for us. And this year, seven billion of us will use twenty‐five trillion kilowatt hours of electricity. An awful lot of that will end up as waste heat. So, we treat waste heat as a problem. We see it as a challenge to design how we can manage it. We don’t think of it as a resource. If we thought of it as a resource, that would be results we are just throwing away.

Our bridges, motorways, tunnels, and dams, and all the buildings that make up our infrastructure are vital to our society and economic growth yet we take them for granted. The shocking truth is that our infrastructure is crumbling beneath our feet. And this is costing us dearly, both in terms of money and carbon.

Why do we do the things that we do? Why do we sometimes choose to be loving parents and other times engage in irrational self‐destructive behaviors? What drives us to sometimes be altruistic and other times make decisions that really threaten our very survival? Well, the answer lies in our brains. Our brains evolved to ensure that we repeat behaviors that will lead to our survival.

Over the past century, we’ve been to the moon, we’ve split the atom, we’ve sequenced the human genome, but were still only at the very beginning of our understanding of the human brain. This is one of the great challenges that we face. If we can understand the brain, we can develop better treatments for brain disorders, we can design better robots, better computers, and ultimately we can better understand ourselves.

From vast data centers to mobile phones, the power of computers continues to transform our lives. But there are some problems across artificial intelligence, in the design of new materials, pharmaceuticals, and clean energy devices that they will simply never solve. So even if we turned our entire planet into a giant supercomputer we wouldn’t be able to solve these and many other important problems. The good news is that if we could build a computing device based on fundamental quantum principles, we could.

The key molecule of optogenetics is a light‐sensitive protein called channelrhodopsin, which is extracted from green algae. Scientists can insert channelrhodopsin into memory cells. Subsequently, scientists can even activate these with blue light which they deliver deep inside the brain with optic fibers.

The face is a constant flow of facial expressions. We react and emote to external stimuli all the time. And it is exactly this flow of expressions that is the observable window to our inner self. Our emotions, our intentions, attitudes, moods. Why is this important? Because we can use it in a very wide variety of applications.

If we want to continue increasing the performance of our computers, we need to rethink the way we compute. And our brains are wonderful proof that impressive computations can be carried out with a very low power budget.

As we began this work in 1987, 1990, going through that period, 3D printers were pretty clumsy. But now they’re cheaper, they’re much more precise and much more accurate. So, [now] we can actually print the chemicals for a battery.
