No sane, rational, and sufficiently-educated person puts forward arguments incompatible with science.
The problem with this statement is that it puts 99.999% of everyone 'beyond the pale'. It disallows meaningful conversations about things which have huge functional impacts on all humans, but about which science has little of use or coherence to say. It cripples conversation about things which our current science deems impossible, without allowing for the certainty that key aspects of what is currently accepted science will be superseded in the future.
In other words, it is an example of a reasonable sounding thing to say that is almost perfectly useless. You have argued yourself into a box.
I would suggest that no sane, rational and sufficiently-educated person ascribes zero probability to irrational seeming propositions.
Infants do not possess many inborn categories, if they have any at all. They perceive the world as directly as their senses permit. But they do not remain this way for long.
This seems to be objectively untrue. Many ingenious experiments with very young children forcefully suggest a wide range of inborn categories, including faces,. There is even evidence that male and female children pay different attention to different categories long before they can talk.
Further, there is strong evidence that children have inborn expectations of relationships between sensory input. The physics of the eye ensures that images focussed on the retina are upside-down, and experiment shows that, for a few days, this is how the world is perceived. But babies learn to invert the image, so that it tallies with reality. This happens automatically, and within days - presumably through some hard-wired expectation of the interrelation between senses - eg proprioception and sight.
As an architect and sometime builder, as an excellent procrastinator, I heartily concur with this comment.
The range of biases, psychological and 'structural' factors at work is wide. Here are a few:
'tactical optimism' : David Bohm's term for the way in which humans overcome the (so far) inescapable assessment that; 'in the long run, we're all dead'. Specifically, within the building industry, rife with non-optimal ingrained conditions, you wouldn't come to work if you weren't an optimist. Builders who cease to have an optimistic outlook go and find other things to do.
maintaining flexibility has benefits: non-trivial projects have hidden detail. It often happens that spending longer working around the project - at the
So many of the comments here seem designed to illustrate the extreme difficulty, even for intelligent humans interested in rationality, and trying hard to participate usefully in a conversation about hard-edged situations of perceived non-trivial import, to avoid fairly simplistic anthropomorphisms of one kind or another.
Saying, of a supposed super-intelligent AI - one that works by being able to parallel, somehow, the 'might as well be magic' bits of intelligence that we currently have at best a crude assembly of speculative guesses for - any version of "of course, it would do X", seems - well - foolish.
Whether or not the AI finds the abstraction of human happiness to be pertinent, and whether it considers increasing it to be worthwhile sacrificing other possible benefits for, are unpredictable, unless we have succeeded in achieving EY's goal of pre-destining the AI to be Friendly.
Surely the discussion is not about the issue of whether an AI will be able to be sophisticated in forming abstractions - if it is of interest, then presumably it will be.
But the concern discussed here is how to determine beforehand that those abstractions will be formed in a context characterised here as Friendly AI. The concern is to pre-ordain that context before the AI achieves superintelligence.
Thus the limitations of communicating desirable concepts apply.
A utility function measured in dollars seems fairly unambiguously to lead to decisions that are non-optimal for humans, without a sophisticated understanding of what dollars are.
Dollars mean something for humans because they are tokens in a vast, partly consensual and partially reified game. Economics, which is our approach to developing dollar maximising strategies, is non-trivial.
Training an AI to understand dollars as something more than data points would be similarly non-trivial to training an AI to faultlessly assess human happiness.
Surely this is not an example of search-space compression, but an example of local islands of fitness within the space? Evolution does not 'make observations', or proceed on the basis of abstractions.
An even number of legs 'works best' precisely for the creatures who have evolved in the curtailed (as opposed to compressed) practical search space of a local maxima. This is not a proof that an even number of legs works best, period.
Once bilateral symmetry has evolved, the journey from bilateralism to any other viable body plan is simply too difficult to traverse. Nature DOES search the fringes of the space of centipedes with an odd number of legs- all the time.... (read more)
This comment crystallised for me the weirdness of this whole debate (I'm not picking sides, or even imagining that I have the capacity to do so intelligently).
In the spirit of the originating post, imagine two worms are discussing the likely characteristics of intelligent life, some time before it appears (I'm using worms as early creatures with brains, allowing for the possibility that intelligence is a continuum - that worms are as far from humans as humans are from some imagined AI that has foomed for a day or two);
Worm1: I tell you it's really important to consider the possibility that these "intelligent beings" might want all the dead leaf matter for themselves,... (read more)
... the general take on climate change here.
Please read a little more before voting this down - I am not looking to initiate a debate on climate change - merely to understand what goes on when it is mentioned.
Disclosure: I am personally concerned about the impact of climate change in the medium term; I am largely convinced it is caused by human activity; I can get moralistic about it. I won't push any of that in this discussion.
I am a relatively recent habituee of the these fora, and mostly I find it full of entertaining, intelligent people talking thoughtfully about things that interest/concern me. I'm pleased - this is rare. Thanks, all.

I envisage a kind of structured wiki, centred around the creation of propositions, which can be linked to allow communities of interest to rapidly come to fairly sophisticated levels of mutual understanding; the aim being to foster the development of strong groups with confidence in shared, conscious positions. This should allow significant confidence in collaboration.
Some aspects, in no particular order;
It's been a few years, but the answer is now - yes. Here's a link to a New Scientist article from earlier this year. I'm afraid there's a pay barrier: https://www.newscientist.com/article/2083706-my-minds-eye-is-blind-so-whats-going-on-in-my-brain/ The article documents recent experiments and thinking about people who are poor or incapable (about 2 to 3% report this) of forming mental pictures (as opposed to manipulating concepts).
