In the adrenaline rush to create a mind-blowing new technology (and profit from it directly or indirectly), ethical questions can be lost in an institutional fog and in competition among companies and countries. Richard Feynman certainly felt he’d misplaced his moral compass in just such a way during the Manhattan Project. 

The attempt to create Artificial General Intelligence is something of a Manhattan Project for the mind, and while the point is the opposite of destruction, some believe that even if it doesn’t end humans with a bang, AGI may lead our species to a whimpering end. The main difference today is those working on such projects seem keenly aware of the dangers that may arise while we’re harnessing the power of these incredible tools. That doesn’t mean the future is assured–there’ll be twists and turns we can’t yet imagine–but it’s a hopeful sign.

Bloomberg Neural Net reporter Jack Clark conducted a smart Q&A with DeepMind CEO Demis Hassabis, discussing not only where his work fits into the scheme of Alphabet but also the larger implications of superintelligence. An excerpt:

Question:

You’ve said it could be decades before you’ve truly developed artificial general intelligence. Do you think it will happen within your lifetime?

Demis Hassabis:

Well, it depends on how much sleep deprivation I keep getting, I think, because I’m sure that’s not good for your health. So I am a little bit worried about that. I think it’s many decades away for full AI. I think it’s feasible. It could be done within our natural lifetimes, but it may be it’s the next generation. It depends. I’d be surprised if it took more than, let’s say, 100 years.

Question:

So once you’ve created a general intelligence, after having drunk the Champagne or whatever you do to celebrate, do you retire?

Demis Hassabis:

No. No, because …

Question:

You want to study science?

Demis Hassabis:

Yeah, that’s right. That’s what I really want to build the AI for. That’s what I’ve always dreamed about doing. That’s why I’ve been working on AI my whole life: I see it as the fastest way to make amazing progress in science.

Question:

Say you succeed and create a super intelligence. What happens next? Do you donate the technology to the United Nations?

Demis Hassabis:

I think it should be. We’ve talked about this a lot. Actually Eric Schmidt [executive chairman of Alphabet, Google’s parent] has mentioned this. We’ve talked to him. We think that AI has to be used for the benefit of everyone. It should be used in a transparent way, and we should build it in an open way, which we’ve been doing with publishing everything we write. There should be scrutiny and checks and balances on that.

I think ultimately the control of this technology should belong to the world, and we need to think about how that’s done. Certainly, I think the benefits of it should accrue to everyone. Again, there are some very tricky questions there and difficult things to go through, but certainly that’s our belief of where things should go.•

Industrial robots are built to be great (perfect, hopefully) at limited, repetitive tasks. But with Deep Learning experiments, the machines aren’t programmed for chores but rather to teach themselves to learn how to master them from experience. Since every situation in life can’t be anticipated and pre-coded, truly versatile AI needs to autonomously conquer obstacles that arise. In these trials, the journey has as much meaning–more, really–than the destination.

Of course, not everyone would agree that humans are operating from such a blank slate, that we don’t already have some template for many behaviors woven into our neurons–a collective unconsciousness of some sort. Even if that’s so, I’d think there’ll soon be a way for robots to transfer such knowledge across generations.

One current Deep Learning project: Berkeley’s Brett robot, designed to be like a small child, though a growing boy. The name stands for “Berkeley Robot for the Elimination of Tedious Tasks,” and you might be tempted to ask how many of them it would take to screw in a light bulb, but it’s already far beyond the joke stage. As usual with this tricky field, it may take longer than we’d like for the emergence of such highly functional machines, but perhaps not as long as we’d expect.

Jack Clark of Bloomberg visited the motherless “child” at Berkeley and writes of it and some of the other current bright, young things. An excerpt from his report:

What makes Brett’s brain tick is a combination of two technologies that have each become fundamental to the AI field: deep learning and reinforcement learning. Deep learning helps the robot perceive the world and its mechanical limbs using a technology called a neural network. Reinforcement learning trains the robot to improve its approach to tasks through repeated attempts. Both techniques have been used for many years; the former powers Google and other companies’ image and speech recognition systems, and the latter is used in many factory robots. While combinations of the two have been tried in software before, the two areas have never been fused so tightly into a single robot, according to AI researchers familiar with the Berkeley project. “That’s been the holy grail of robotics,” says Carlos Guestrin, the chief executive officer at AI startup Dato and a professor of machine learning at the University of Washington.

After years of AI and robotics research, Berkeley aims to devise a system with the intelligence and flexibility of Rosie from The Jetsons. The project entered a new phase in the fall of 2014 when the team introduced a unique combination of two modern AI systems&and a roomful of toys—to a robot. Since then, the team has published a series of papers that outline a software approach to let any robot learn new tasks faster than traditional industrial machines while being able to develop the sorts of broad knowhow for solving problems that we associate with people. These kinds of breakthroughs mean we’re on the cusp of an explosion in robotics and artificial intelligence, as machines become able to do anything people can do, including thinking, according to Gill Pratt, program director for robotics research at the U.S. Defense Advanced Research Projects Agency.
