DID YOU KNOW? NASA’S Curiosity Mars Rover is equipped with a narrow AI that allows it to choose its own rock samples<br />

Scientist Rodney Brooks is<br />

inspired by advances in<br />

neuroscience, and<br />

presents the potential<br />

benefits of building<br />

artificial neural networks.<br />

An IBM-built machine,<br />

named Deep Blue, defeats<br />

world chess champion<br />

Garry Kasparov. For some,<br />

Deep Blue’s ability to act<br />

strategically and evaluate<br />

up to 200 million<br />

positions a second<br />

showed the true power<br />

of AI. For others, the<br />

task still lay ahead, as<br />

Deep Blue had merely<br />

shown a computer’s<br />

effectiveness at<br />

handling a very<br />

specialised task.<br />

2008<br />

Google’s voice recognition<br />

software utilises artificial<br />

neural networks to lift its<br />

accuracy to over 80 per cent.<br />

2011<br />

An IBM machine makes<br />

history once again, as<br />

Watson defeats its human<br />

competitors on the US quiz<br />

show Jeopardy. This feat is a<br />

significant milestone for AI<br />

and one much harder<br />

than programming a<br />

computer to win at<br />

chess. In order to<br />

answer riddles and<br />

complex questions,<br />

Watson is designed<br />

using neural networks<br />

and extensively trained to<br />

recognise patterns.<br />

daunting, but we shouldn’t be as nervous about<br />

this possible future as many are – permitting, of<br />

course, that we progress sensibly.<br />

A super artiicial intelligence won’t pose a<br />

danger to us by itself; at least, not in the way we<br />

think it will. In the many apocalyptic scenarios<br />

shown in iction, the AI thinks like us, and<br />

sometimes even feels like us. They share our<br />

ambitions and quests for freedom and<br />

dominance. But in reality, this wouldn’t be the<br />

case. A computer’s mind works completely<br />

diferently to yours and mine, and that would be<br />

true even for a particularly clever artiicial brain.<br />

<strong>It</strong>’s easy to imagine that whatever is the<br />

smartest organism will want to climb to the top<br />

of the food chain, especially if we think about<br />

how we got here. But computers aren’t products<br />

of evolution, and that means they’ll have little in<br />

common with us. All of our wants and needs<br />

come from our genetic blueprint, and fortunately<br />

for us (and maybe for the machines too) they will<br />

be free from these desires. This might be<br />

confusing to consider; after all, it’s very hard to<br />

imagine something outside of our own<br />

perspective. But a computer will only exist to<br />

serve its programming, and that will be<br />

whatever it is that we command it to be. So that’s<br />

one aspect we don’t need to worry about.<br />

Unfortunately, it doesn’t mean that we’re<br />

completely in the clear. Say we’re able to one day<br />

create a super intelligence, and we command it<br />

to help us terraform Mars into a suitable home. <strong>It</strong><br />

may create solutions that would have taken us<br />

centuries to generate by ourselves, and it could<br />

help us make our dream a reality. But it may also<br />

decide that the best way to terraform Mars is to<br />

take Earth’s atmosphere and resources and<br />

transport them there. The intelligence would be<br />

doing as commanded, but it would be to our<br />

detriment. Ensuring that it correctly<br />

understands what we’re asking may well be the<br />

diference between humanity reaching the stars<br />

and facing extinction.<br />

The second threat of AI is more immediate,<br />

and that’s using its power to beat a diferent<br />

challenge: cracking code. If an able intelligence<br />

falls into the wrong hands, it could be trained to<br />

break through all sorts of password-protected<br />

programmes. So this too is something we have to<br />

be very careful of. But in spite of these potential<br />

problems, artiicial intelligence could well<br />

transform our lives for the better.<br />

“In science fiction, AI thinks, and<br />

sometimes even feels, like us”<br />

OTHER CLEVER ROBOTS<br />

2014<br />

A programme called Eugene<br />

Goostman successfully<br />

passes a variation of the<br />

Turing test, a measure of<br />

machine ‘intelligence’.<br />

2016<br />

Google DeepMind’s AlphaGo is<br />

victorious over Go grandmaster<br />

Lee Sedol. Unlike IBM’s Deep<br />

Blue, AlphaGo could not<br />

employ a ‘brute force’<br />

approach, where every<br />

possible move is<br />

programmed into the<br />

computer. Instead, the<br />

programme makes use<br />

of machine learning to<br />

practice over millions<br />

of games until it learns<br />

its own winning strategy.<br />

Cosmo<br />

This little companion is full<br />

of character and uses AI to<br />

enrich his personality. He<br />

can interact with his<br />

surroundings, play games<br />

and throw tantrums, all<br />

thanks to robotics and<br />

machine learning.<br />

Sphero BB-8 Droid<br />

Although not quite at the level of the droid found in a<br />

galaxy far, far away, Sphero’s BB-8 is a clever roller.<br />

Primarily app controlled, it’s able to act autonomously<br />

and evolve its personality as it interacts with you.<br />

NAO<br />

This small humanoid<br />

robot stands at only<br />

58cm tall, but is designed<br />

as a cute and friendly<br />

companion. And just like<br />

it’s larger humanoid<br />

cousins, it can walk and<br />

sense its surroundings.<br />
