Alva Noe: Don't Worry About the Singularity, We Can't Even Copy an Amoeba

Prune Re:Don't need amoebae to fly (286 comments)

What could be more dangerous than building AI that's smarter than us but cannot relate to us because its intelligence is drastically different from ours? There's no fool-proof way to actually implement "software" constraints in a general super-human intelligence AI (Asimov's robotics laws are about the most unrealistic thing I've ever read in sci fi), and the safety factor falls even further over generations as you get the AI to design an even smarter AI. Physical constraints? Do you think that when an ultra-intelligent AIs are available, businesses won't connect them to as many control systems as possible to profit from improved efficiencies and replaced labor? And what is more inefficient than some sort of "air gap"?

The best bet is to implement AI that can understand us, and since human cognition is completely intertwined with feelings/emotions at a basic neurological level (see somatic markers, etc.) this requires making human-like AI that can feel the way we feel, so that it can have consciousness that is sufficiently similar to ours. This is a very hard problem and requires simulating a human-like brain _and_ also the body that goes with it (see embodied cognition on wiki). If we build powerful AIs that don't love us, then humanity will be doomed.

Alva Noe: Don't Worry About the Singularity, We Can't Even Copy an Amoeba

Prune Re:Consciousness versus Intelligence (286 comments)

But our bodies are one of the most essential determinants of the nature of human consciousness: http://en.wikipedia.org/wiki/E...

This is far more than a philosophical thesis; it's backed up by neuroscience. I highly suggest you read Damasio, who's one of the top neuroscientists in the world. A good overview can be found in his book Self Comes to Mind, the price of it being justified by the selection of paper references in the endnotes alone.

Alva Noe: Don't Worry About the Singularity, We Can't Even Copy an Amoeba

Prune Re:Armchair cognitive scientist (286 comments)

Your simulation is of purely academic interest if it relies the usual gross oversimplification of the activity of a real neuron. It's only two years ago that we've even attempted a simulation of 100 trillion synapses (comparable to a human brain), in a joint IBM and Lawrence Livermore National Laboratory project. That simulation ran on what was in 2012 the top supercomputer in the world, yet the simulation still ran over 1500 times slower than real-time, and, worse, was still using quite simplified neuron models! Having a brain-equivalent information processor that fits in the space of a skull and runs on the brain's approximately 20 W? It won't happen in your life time if you're old enough to be posting on this site.

Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans

Prune It applies to humans as well (317 comments)

By the Bekenstein bound (http://en.wikipedia.org/wiki/Bekenstein_bound), human brains can contain only a finite number of distinguishable quantum states. This means that the brain's information processing has the same limits as a nondeterministic linear bounded automaton, which is more restricted than a Turing machine. We can't think anything more than a sufficiently sophisticated computational construction can. The same limits ultimately apply to us that the authors ascribe to their killer robot targets.

City of Toronto Files Court Injunction Against Uber

Prune Re:Don't go the way of Vancouver (168 comments)

Drivers are giving up. Almost every other major North American city has freeways running through or near the city core. Those are part of the infrastructure that invites city centres to become focal points of business, commerce, and finance. Vancouver's residential core cements the city's status as a place where wealth made elsewhere is spent; none is actually generated here. I can only pray that the feds force through the pipeline so that the port can expand, and offset some of this failure. Even much of the high tech industry ran off to Quebec and Ontario, despite high hipster quotient.

Prune Re:Don't go the way of Vancouver (168 comments)

And when he gets discouraged by how our buses are never on time, or how the Skytrain (Vancouver's light rail) has its tracks under maintenance far too often during active hours, maybe he can instead make use of recently-reelected-Mayor-Moonbeam's pet project bicycle lanes — I mean, he'd be meaningfully increasing bike ridership statistics and maybe I'll feel a teensy bit better about the traffic disruption the bike lanes have caused downtown and in other communities in a city that is becoming ever more _not_ a commerce, technology, or industrial centre, but a residential playground for the wealthiest in the international real estate market.

City of Toronto Files Court Injunction Against Uber

Prune Mod parent down (168 comments)

Not simply because his post is wrong (that is not considered grounds for moderation by itself), but because it's willful ignorance and grossly insulting to readers. His post is, in essence,

"The article contains this trivially verifiable statement of fact, but I _feel_ it doesn't sound right to me, so I'm compelled to rant about it on Slashdot, while at the same time being far too lazy to spend ten seconds to check it with a search engine — but then again, I just don't respect the audience enough to care if I post total nonsense; all that matters is that I get to express my feelings, and who the hell are Slashdot readers to tell me my feelings are wrong anyway?!"

Former Police Officer Indicted For Teaching How To Pass a Polygraph Test

Prune Mod parent down for trolling (328 comments)

Hit a nerve, did he? And with an ID three times lower than yours, I'd say that the chance Sycraft-fu is a troll after all his time on Slashdot, rather than actually speaking his mind, is next to nil (even though I often disagree with many of his views, something the moderating rules rightly specify you can't use as a basis of moderation). As for you, I've been reading your posts for some time, and can say that you calling someone else a troll is the height of hypocrisy. The painful truth is that you want him downmoderated because you disagree with his views, and — given the impassioned language of your post — your disagreement is pretty personal. If you get butthurt so easily, perhaps you should go to another discussion forum.

81% of Tor Users Can Be De-anonymized By Analysing Router Information

Prune Re:The only solution I can think of (136 comments)

Wouldn't adding random timing jitter to the packets deal with the problem without using up more network resources with junk data? As long as the timing noise distribution between routers is not grossly dissimilar, that should work.

Ubisoft Points Finger At AMD For Assassin's Creed Unity Poor Performance

Prune Re:Or, you know, use OpenGL (262 comments)

Mod parent down for not knowing that in the OpenGL specification documents the "gl" prefix that you otherwise find in actual code is omitted. The call has been available in NVIDIA and AMD drivers since the second half of last year, and is documented in the spec: https://www.opengl.org/registr... see "MultiDrawElementsIndirectCountARB" (again, the "gl" part is always omitted in spec documents). You dun goofed now, AC, and embarrassed yourself. So no, the actual call is not glMultiDrawElementsIndirect and is nowhere as restricted, because it has the critical difference that the count to draw is now also stored in a GPU buffer and thus can be written by the GPU. Combined with the bindless graphics NVIDIA extension and bindless textures in OpenGL 4.4, you can even set up the whole scene graph on the GPU. Finally, as for my experience--(re)writing a graphics engine is exactly what my team is doing. By the way, maybe you should post your comment also at the official opengl forums so the rest of us can too have a good laugh.

Prune Or, you know, use OpenGL (262 comments)

One draw call, glMultiDrawElementsIndirectCountARB(), per shader program (you can even avoid that by using shader subroutines so you're then doing one draw call per render pass).

Canadian Police Recommend Ending Anonymity On the Internet

Prune Re:ROFL (231 comments)

It's not the RCMP; it's the Ontario Provincial police. Your joke doesn't work nearly as well when this story is about a mere regional police force and has no implications as to state policy.

Canadian Police Recommend Ending Anonymity On the Internet

Prune Re:Reading comprehension check (231 comments)

This was the Ontario police, not the RCMP, and Ontario is governed by the Liberals. So, Vic and the other federal Conservatives have nothing to do with this. I bet you're not about to correct yourself and redirect your hate speech to your beloved Liberals, because, after all, you feel no shame in holding a double standard, amirite?

Canadian Police Recommend Ending Anonymity On the Internet

Prune Re:Religion (231 comments)

Regarding your signature, I've got (old) news for you: absence of evidence is not evidence of absence because Popperian epistemology won, and evidence's only utility is for falsification and cannot be used to argue for an increased probability a theory is correct. The issue was argued into the 90s by people like Elby, but the outcome was clear at least a decade earlier. http://en.m.wikipedia.org/wiki...

The Math Behind the Hipster Effect

Prune Mod parent up (176 comments)

This paragraph alone is enough to make a +5 post:

Hipsterism is the practice of misdirection. Hipsters are lame people who have learned that attention is the scarcest human resource, so they can hide behind a few attention-grabbing quirks. It saves them from having to do anything actually interesting, useful or productive.

First commercial carbon capture project is failing

Prune (557140) writes "A Saskatchewan report that the world's first commercial carbon capture project is failing could be grave news for those involved in efforts to blunt humanity's contribution to climate change.
