When I saw the picture, I assumed she was the woman you described in one of your Bayesian conspiracy stories that you post here. But then, she was in a pink jumpsuit, and had, I think, blond hair.

@Daniel_Franke: I was just describing a sufficient, not a necessary condition. I'm sure you can ethically get away with less. My point was just that, once you can make models that detailed, you needn't be prevented from using them altogether, because you wouldn't necessarily have to kill them (i.e...(read more)

@Tim_Tyler:

<blockquote>The main problem with death is that valuable things get lost.

Once people are digital, this problem tends to go away - since you can relatively easily scan their brains - and preserve anything of genuine value.

In summary, I don't see why this issue would be much of a prob...(read more)

Khyre: <i>Setting or clearing a bit register regardless of what was there before is a one-bit irreversible operation (the other two one-bit input, one-bit output functions are constant 1 and constant 0).</i>

*face-palm* I can't believe I missed that. Thanks for the correction :-)

Anyway, with tha...(read more)

I'm going to nitpick (mainly because of how much reading I've been doing about thermodynamics and information theory since your engines of cognition post):

<blockquote>Human neurons ... dissipate around a million times the heat per synaptic operation as the thermodynamic minimum for a one-bit opera...(read more)

Nick_Tarleton: I think you're going a bit too far there. Stability control theory had by that time been rigorously and scientifically studied, dating back to Watts's flyball governor in the 18th century (which controlled shaft rotation speed by allowing a ball to swing out and increase rotational i...(read more)

@Scott_Aaronson: Previously, you had said the problem is solved with *certainty* after O(1) queries (which you had to, to satisfy the objection). Now, you're saying that after O(1) queries, it's merely a "high probability". Did you not change which claim you were defending?

Second, how can the re...(read more)

Could Scott_Aaronson or anyone who knows what he's talking about, please tell me the name of the n/4 left/right bits problem he's referring to, or otherwise give me a reference for it? His explanation doesn't seem to make sense: the deterministic algorithm needs to examine 1+n/4 bits only in the wo...(read more)

Someone please tell me if I understand this post correctly. Here is my attempt to summarize it:

"The two textbook results are results specifically about the worst case. But you only encounter the worst case when the environment can extract the maximum amount of knowledge it can about your 'expert...(read more)
