		<description>&quot; â€œIt certainly looks like a piece of research that will contribute, in the medium-long term, to the goal of tiling the universe with paper clips.â€

But you think this of concrete advances in AGI research in general right?&quot;

 - well, it does depend upon whether the result is more or less likely to be used by a careful team of FAI developers, rather than by a misathropic team who don&#039;t really care whether they kill the human race.</description>

		<description>&quot;and who would fund them if they donâ€™t publish their research?&quot;

 - the funding agencies would have to be persuaded of the risks of AGI. Actually, beaurocrats might like the idea of having loads of control over academics, so it might be easier to get them on side.</description>

		<description>Though I don&#039;t think the &quot;key&quot; to AI lies within the realm of maths or logic,  &lt;a href=&quot;http://golem.ph.utexas.edu/category/2009/09/towards_a_computeraided_system.html&quot; rel=&quot;nofollow&quot;&gt;other approches&lt;/a&gt; to computerized mathematics seem to me of more import than AIXI.

And don&#039;t worry about &quot;paper clips&quot;, entropy will take care of snuffing out the hubris of us demented monkeys.</description>

		<description>&quot;It certainly looks like a piece of research that will contribute, in the medium-long term, to the goal of tiling the universe with paper clips.&quot;

But you think this of concrete advances in AGI research in general right?

&quot;Incidentally, how likely do you think AGI academics are to agree to the idea of not publishing their research for safety reasons?&quot;

Even if most did agree to this, information tends to get out, other people working in close areas discover the same things a few years later, alternative methods are found that do the same thing... and who would fund them if they don&#039;t publish their research?  Come to think of it, what if we all stopped telling each other about our research?  15 years from now somebody like Hutter out of the blue announces that he&#039;s built a machine with clearly super human intelligence.  And no, he&#039;s still not going to tell you how he did it... for safety reasons.  Does this really help from your perspective?

AGI is coming fast.  I read this morning that IBM is already talking to astronomers about putting together an exa-flop machine for them before 2020, building on the work for their 20 peta-flop machine that&#039;s coming out in the next couple of years.</description>

		<description>I wouldn&#039;t be surprised if they do get to run it on a supercomputer, or at least a decent cluster, in the coming years.  Most supercomputer labs are pretty open to donating limited amounts of time to such things.

There are some quite basic types of pattern learning that this design would struggle with due to the somewhat limited nature of CTW.  For example, it can&#039;t build proper hierarchies of abstraction about its environment and thus it can&#039;t really do anything &quot;deep&quot;.  Nevertheless, it would be interesting to see how this type of simple design tops out in practice as you add more computer power.  That would help clarify the system&#039;s most serious limitations and perhaps point to where more future research might be useful.

MC-AIXI is certainly no Skynet!  :-)  But, at least to my mind, it looks like an interesting starting point for future work.</description>

		<description>&quot;I doubt that it poses a serious existential risk.&quot;

I think the ghosts in pac-man would disagree.</description>

		<description>&quot; It would be interesting to see what it was capable of on a supercomputer with ten thousand times the resources of their desktop PC.&quot;

 - why don&#039;t we set up a SKYNET@HOME distributed uFAI initiative to find out?</description>

		<description>@Vladimir:  This approach is a very obvious thing to do once you have AIXI, and I doubt that it poses a serious existential risk.</description>
