Hardware, Embedded Systems Artificial intelligence is still a long way from delivering the human intelligence in robot form that has long been common in science fiction.

In my mind, we've already successfully achieved artificial intelligence for many years now. Everything from everyday automatic sliding doors to computer fingerprint analysis to artificial aircraft pilots are really in the realm of "Artificial Intelligence", that is intelligence from artificial origin.

Some technology may already be more intelligent than average humans, especially within speciality domains.

I think the reasons people are disappointed with AI today are threefold:

1. It's artificial.
This may seem dubious, but many people don't consider computers intelligent BECAUSE their intelligence was programmed by a human. They want to see intelligence from a self learning computer. And I think we're starting to see more progress on that as computers get more powerful.

2. It's virtual.
A computer game clearly can exhibit intelligence, but it's less realistic because it's on screen. Developers are accustomed to abstracting concepts, and I believe we, as developers, can appreciate abstracted intelligence more than a typical person can. If the exact same intelligence found in sophisticated AI could be projected into the real world, it suddenly feels less "artificial".


3. It's not conscious.
The role of consciousness as it relates to AI is poorly understood. The truth is we don't know if any AI can truly be conscious. Sure it could act as though it were conscious, it may even have learned how to act consciously by learning how to emulate humans on it's own, but even then I'd have trouble overlooking the fact that it's just a bunch of sophisticated deterministic algorithms - it can't "feel" anything, can it?

On the other hand, if an alien creature came to earth and claimed to be conscious, most of us wouldn't even second guess that, but how would we know it wasn't lying? If it was sufficiently intelligent, it could easily fool any of us into believing it were conscious.


Perhaps this is what people are looking for with AI, an intelligence that can fool us into believing a computer is conscious.

Edit:
How exactly would it be possible for an AI to prove it's own consciousness? Sceptics like myself would always point to the code and say that it's *emulating* consciousness without *being* conscious.

The computer characters in a game act dumber than dogs. Being on screen has nothing to do with it. Actors in a movie don't come across as dumb.
When a computer can learn a new language like a 0-6 year old child can do. When you computer understands what you are doing. When a computer can drastically improve over time without a programmer. That is when you can call it intelligent IMO.

You need to look at a bigger picture. Nothing improves over time in isolation. Despite the fact that a lot of our intelligent machinery is coded in DNA (biological computer program) we still require massive amounts of input from our parents, school teachers, books, society, etc. All these external factors continually program our brains over many years. Otherwise, how do you tell the difference between good and evil, or courage and cowardice?

Complex AI is definitely possible, but will need a lot of research, development and evolution before it can overtake human intelligence.

So virtually all primates cannot be called intelligent? (likewise cetaceans, cats, dogs, going through many tool-making & using birds, "down" to octopuses or even swarm intelligence of some insects)

It's a spectrum. And humans find it very hard to "drastically improve over time without a programmer" - there are enough cases of severely neglected children and effects of it, even some feral children (while most of such stories are made up, there are few rigorously documented ones, for example: http://en.wikipedia.org/wiki/Genie_(feral_child) ).
IQ and fertility rate are inversely correlated ...might be also because of more focus each individual child can get, when there is less of them.

Well, when you mix some good (at being "realistic") deathmatch FPS bots with average human players, immediately telling them apart is not always so clear.

Fergy,

"Actors in a movie don't come across as dumb."

Interesting, but the actors in a movie are just following a script, and to that extent I would argue they ARE dumb in this respect since following a script does NOT require intelligence.

You can nitpick and say they need to be able to read the scripts and interact with other actors in order to do their jobs (which requires some intelligence). However actors don't technically have to understand a script, so that's setting a very low bar for "intelligence" in my opinion. One which computers could probably achieve in the short term if it weren't for the virtual/physical barrier I spoke about earlier.
