Mary Shelley, Frankenstein’s monster and artificial life

Shortly after Ada Lovelace was born, so long before she made predictions about future “creative machines”, Mary Shelley, a friend of her father (Lord Byron), was writing a novel. In her book, Frankenstein, inanimate flesh is brought to life. Perhaps Shelley foresaw what is actually to come, what computer scientists might one day create: artificial life.
Life it may not be, but engineers are now doing pretty well in creating humanoid machines that can do their own thing. Could a machine ever be considered alive? The 21st century is undoubtedly going to be the age of the robot. Maybe it’s time to start thinking about the consequences in case they gain a sense of self.
Frankenstein was obsessed with creating life. In Mary Shelley’s story, he succeeded, though his creation was treated as a “Monster” struggling to cope with the gift of life it was given. Many science fiction books and films have toyed with these themes: the film Blade Runner, for example, explored similar ideas about how intelligent life is created; androids that believe they are human, and the consequences for the creatures concerned.
Is creating intelligent life fiction? Not totally. Several groups of computer scientists are exploring what it means to create non-biological life, and how it might be done. Some are looking at robot life, working at the level of insect life-forms, for example. Others are looking at creating intelligent life within cyberspace.
For 70 years or more scientists have tried to create artificial intelligences. They have had a great deal of success in specific areas such as computer vision and chess playing programs. They are not really intelligent in the way humans are, though they are edging closer. However none of these programs really cuts it as creating “life”. Life is something more than intelligence.
A small band of computer scientists have been trying a different approach that they believe will ultimately lead to the creation of new life forms: life forms that could one day even claim to be conscious (and who would we be to disagree with them if they think they are?) These scientists believe life can’t be engineered in a piecemeal way, but that the whole being has to be created as a coherent whole. Their approach is to build the basic building blocks and let life emerge from them.
The outline of the idea could be seen in the game Sodarace, where you could build your own creatures that move around a virtual world, and even let them evolve. One approach to building creatures, such as a spider, would be to try and work out mathematical equations about how each leg moves and program those equations. The alternative artificial life way as used in Sodarace is to instead program up the laws of physics such as gravity and friction and how masses, springs and muscles behave according to those laws. Then you just put these basic bits together in a way that corresponds to a spider. With this approach you don’t have to work out in advance every eventuality (what if it comes to a wall? Or a cliff? Or bumpy ground?) and write code to deal with it. Instead natural behaviour emerges.
The artificial life community believe, not just life-like movement, but life-like intelligence can emerge in a similar way. Rather than programming the behaviour of muscles you program the behaviour of neurones and then build brains out of them. That it turns out has been the key to the machine learning programs that are storming the world of Artificial Intelligence, turning it into an everyday tool. However, if aiming for artificial life, you would keep going and combine it with the basic biochemistry of an immune system, do a similar thing with a reproductive system, and so on.
Want to know more? A wonderful early book is Steve Grand’s: “Creation”, on how he created what at the time was claimed to be “the nearest thing to artificial life yet”… It started life as the game “Creatures”.
Then have a go at creating artificial life yourself (but be nice to it).
