And so, today I conclude this series of posts on the subject of alternative intelligence (man, I am getting truly sick of writing that word). So far I have dealt with the philosophy, the practicalities and the fundamental nature of the issue, but today I tackle arguably the biggest and most important aspect of AI- the moral side. The question is simple- should we be pursuing AI at all?
The moral arguments surrounding AI are a mixed bunch. One of the biggest is the argument that is being thrown at a steadily wider range of high-level science nowadays (cloning, gene analysis and editing, even synthesis of new artificial proteins)- that the human race does not have the moral right, experience or ability to ‘play god’ and modify the fundamentals of the world in this way. Our intelligence, and indeed our entire way of being, has evolved over thousands upon millions of years of evolution, and has been slowly sculpted and built upon by nature over this time to find the optimal solution for self-preservation and general well being- this much scientists will all accept. However, this argument contends that the relentless onward march of science is simply happening too quickly, and that the constant demand to make the next breakthrough, do the next big thing before everybody else, means that nobody is stopping to think of the morality of creating a new species of intelligent being.
This argument is put around a lot with issues such as cloning or culturing meat, and it’s probably not helped matters that it is typically put around by the Church- never noted as getting on particularly well with scientists (they just won’t let up about bloody Galileo, will they?). However, just think about what could happen if we ever do succeed in creating a fully sentient computer. Will we all be enslaved by some robotic overlord (for further reference, see The Matrix… or any other of the myriad sci-fi flicks based on the same idea)? Will we keep on pushing and pushing to greater endeavours until we build a computer with intelligence on all levels infinitely superior to that of the human race? Or will we turn robot-kind into a slave race- more expendable than humans, possibly with programmed subservience? Will we have to grant them rights and freedoms just like us?
Those last points present perhaps the biggest other dilemma concerning AI from a purely moral standpoint- at what point will AI blur the line between being merely a machine and being a sentient entity worthy of all the rights and responsibilities that entails? When will a robot be able to be considered responsible for its own actions? When will be able to charge a robot as the perpetrator of a crime? So far, only one person has ever been killed by a robot (during an industrial accident at a car manufacturing plant), but if such an event were ever to occur with a sentient robot, how would we punish it? Should it be sentenced to life in prison? If in Europe, would the laws against the death penalty prevent a sentient robot from being ‘switched off’? The questions are boundless, but if the current progression of AI is able to continue until sentient AI is produced, then they will have to be answered at some point.
But there are other, perhaps more worrying issues to confront surrounding advanced AI. The most obvious non-moral opposition to AI comes from an argument that has been made in countless films over the years, from Terminator to I, Robot- namely, the potential that if robot-kind are ever able to equal or even better our mental faculties, then they could one day be able to overthrow us as a race. This is a very real issue when confronting the stereotypical issue of a war robot- that of an invincible metal machine capable of wanton destruction on par with a medium sized tank, and who is easily able to repair itself and make more of itself. It’s an idea that is reasonably unlikely to ever become real, but it actually raises another idea- one that is more likely to happen, more likely to build unnoticed, and is far, far more scary. What if the human race, fragile little blobs of fairly dumb flesh that we are, were ever to be totally superseded as an entity by robots?
This, for me, is the single most terrifying aspect of AI- the idea that I may one day become obsolete, an outdated model, a figment of the past. When compared to a machine’s ability to churn out hundreds of copies of itself simply from a blueprint and a design, the human reproductive system suddenly looks very fragile and inefficient by comparison. When compared to tough, hard, flexible modern metals and plastics that can be replaced in minutes, our mere flesh and blood starts to seem delightfully quaint. And if the whirring numbers of a silicon chip are ever able to become truly intelligent, then their sheer processing capacity makes our brains seem like outdated antiques- suddenly, the organic world doesn’t seem quite so amazing, and certainly more defenceless.
But could this ever happen? Could this nightmare vision of the future where humanity is nothing more than a minority race among a society ruled by silicon and plastic ever become a reality? There is a temptation from our rational side to say of course not- for one thing, we’re smart enough not to let things get to that stage, and that’s if AI even gets good enough for it to happen. But… what if it does? What if they can be that good? What if intelligent, sentient robots are able to become a part of a society to an extent that they become the next generation of engineers, and start expanding upon the abilities of their kind? From there on, one can predict an exponential spiral of progression as each successive and more intelligent generation turns out the next, even better one. Could it ever happen? Maybe not. Should we be scared? I don’t know- but I certainly am.
