Robotic Agency
Historically, if we
encountered something that moved toward us, or did much at all, it was safe to assume it was an agent. The more
human-like the behaviour, the more agency we were encountering. As Brian
Cantwell-Smith has noted, until recently if anything spoke to us, we could hope
to take it home for dinner. But these days anything from our cars, to
computers, or artificial intelligences might try and strike up a conversation
with us. Today robots and intelligent devices are able to exhibit all kinds of
behaviours that make them look
as though they are agents, while we can be assured that by my definition above,
they are merely machines.
An example of behaviour that
exposes the problem is Chess playing. This has traditionally been associated
with high human intelligence, and there's no doubt that IBM's chess-playing
system 'Deep Blue' that in 1997 beat the world champion, Kasparov, was a
magnificent technical achievement. As might have been expected, the media
reported that a brave new era of artificial intelligence had begun. But the
researchers themselves saw things differently. According to Senior Manager,
Chung-Jen Tan, "This chess project is not AI", and Joseph Hoane,
"The techniques that tried to mimic human judgment failed miserably. We
still don't know how to do that at all".
So it would be a mistake to
see Deep Blue as performing human-like judgment, even though it can outperform
human judgment when applied to the same task. More importantly, Deep Blue is no
more an agent in the world than an everyday PC.
