Aussie AI boffins let fly with Angry Birds automation code

fizz

It does also need to compute strategies, decide how to use the different bird powers to help the following birds to accomplish the total goal, essentially it does need to properly rcognize complex causal-chains.

If you think that understanding that if I throw a small bird at that anonymous block instead of at that uncovered pig, I will then open a path to throw the bomb-bird at the base of the pillar that falling will knock out the whole lot of pigs included that protected one that I would have no chance to hit does not involve a good level of AI, I don't know what it does...

Even in nature only very few animals, all considered pretty intelligent, understand the concept of causation at more than few steps of separation.

Re: Mid-40s?

This will be instead the secret of its success: 40s something men will pay for their tickets and additional tickets for 20s girls... and as most of the colony will be necessarily automated and there will be a lot of free time and few distractions, people will multiply like rabbits... see Dr.Strangelove final subterranean mines plan...

Is lightspeed really a limit?

Re: Relativity, causality, FTL: Choose two

If timeand speed are not really linked as we think, relativity is not true, and so my statement remains: causality and FTL remains, and relativity goes out of the window.

Said that, relativity have been verified at quite an impressive range of conditions, so to throw it out of the window is not a small task.

Re: Relativity, causality, FTL: Choose two

The part about hoping to live was directed to those that when you speak about FTL suddenly start jumping around all happy like puppies... if causality is not assured, our very existence become very precarious.

Said that, I agree with you that what it is, it is: when exploring nature belief have to remain out of the window.

Relativity, causality, FTL: Choose two

There's also the small problem of causality: if FTL is consistent with relativity, relativity is still true, and FTL is possible, suddenly our concept of causality is thrown out of the window.

As far as I can understand, that does not change with this paper.

Do we really hope to live in an universe where retro-causality is true?

Apple: I love to hate, and hate to love thee

fizz

No addiction...

...simple low-grade hypocrisy: the comfort of the immediate moment is more valuable to you of your ideals.

Oh, it's perfectly natural, everybody does it... the same way people that knows oil is depleting have no troubles driving cars even when not strictly necessary, religion believers routinely sins, etc. etc.

Somebody mask this cognitive dissonance by denying that's a problem in the first place (very common feature in this website), some others recognize it for what it is and struggle to find a balance between inconvenience and what's right.

I would say that, while sharing your beliefs about Apple being bad for the industry, I have absolutely no troubles avoiding their products like plague, but I've to admit that I find their systems quite unusable from my point of view, so that's not a big effort on my side...

'Scientists' seek to set world social, economic, tech policy at Rio+20

Re: What's so damn bloody annoying

A pity that so many economists tend to work under assumptions that do not take into account the real world, i.e. actual people psychology, enthropy, thermodinamics etc. etc.

A fun read:

Re: Been here before

Nope, they predicted the collpase for the second middle of this century.

In fact, according to recent verifications, we're following their most pessimistic forecasts ina remarkably precise way.

Reducing our lifestyles is not a choice for us, it will be only a choice if we will do it the easy way or the hard way.

Oh, and hoping in tech advance to keep out nuts out of the fire indefinitely is an illusion for the math and physics uneducated: do some math and consider implications of exponential growth. It's not a matter of being "green" or "treehugging" or anything, it's a matter of facing reality.
