Both the Schrodinger equation and inflationary cosmology predict alternate worlds filled with alternate yous. MWI refers to the former. The author of this piece is talking about the later.
If anyone is looking for a simple introduction to the Everett interpretation I'll point you to this short lecture by James Ladyman: https://www.youtube.com/watch?v=cgXVEeL9tzM
>It wouldn’t be an exaggeration to say that a front line, if not the trench of the global gender war, is in Silicon Valley. In that sense, Silicon Valley culture echoes the Wolf of Wall Street culture in the ’80s and ’90s.
Signal the right politics and even this nonsense gets upvoted. Scott Alexander wrote about why differences in outcome in highly technical fields might not imply a vast economically-counterproductive misogynistic conspiracy here:http://slatestarcodex.com/2015/01/24/perceptions-of-required...
Reality is under no obligation to live up to our ideals.
OK everyone: At several people’s request, I’ve now taken a look at arXiv:1403.7686, and I can confirm that it’s complete garbage. The author is simply mistaken that solving the Schrödinger equation is “NP-complete” in any interesting sense: his argument for that seems to rely on a rediscovery of the adiabatic algorithm, but he doesn’t mention that the spectral gap could be exponentially small (and hence the annealing time could be exponentially large)—the central problem that’s been the bane of Farhi and his collaborators (and, of course, of D-Wave) for the past 15 years.
Also, even if you thought (for totally mistaken reasons) that quantum mechanics let you solve NP-complete problems in polynomial time, that might (or might not) suggest to you that quantum mechanics should be replaced by something else. But until you’d actually found a replacement, and given some sort of evidence for its truth, I don’t see how you could claim to have thereby “solved the measurement problem”!!
As additional problems, the author appears to conflate the P vs. NP problem with the question of whether NP-complete problems can be efficiently solved in the physical world, a common novice mistake. And also, he seems comically unaware of everything that’s been discovered in quantum computing theory over the past 20 years relevant to the issues he’s writing about—as if he just emerged from a cave.
The problem of the cat is entirely caused by the assumption that experiments only have one outcome, the belief that wave functions can collapse by magic. The Everett interpretation solves the problem.
Your questions are odd. We live in the macro scale, and at this scale classical physics is a great approximation. However, decoherence exists as a prediction of quantum mechanics, which explains why this is the case. What more do you want?
No one has every believed in the basilisk, save for maybe Yud. Everyone on LessWrong thought it was dumb from day one. LessWrong, now mostly dead, was a fun community full of smart people. That article is trying to make the place out as a cult, but no one bought any of that stuff, not even Roko. He was just playing around with local memes. It's pretty gross how this whole basilisk thing has turned out.
It's assumed a rational agent judges its actions by how likely said action are to align the world with their fundamental values. For this reason, it is argued, a rational agent will not change its terminal goals. For example, suppose we build an agent that desires only to make shoes. That is, its ideal universe would consist of all available matter being converted into sneakers. Would it realize this is stupid? No. It judges it actions and thoughts only by how many shoes they are likely to bring into being. Any thought against this would be judged, correctly, as a negative contribution to shoe production and so wouldn’t be implemented, and likely would remain unthought.
The best paper on this by far it Basic AI Drives by Stephen M. OMOHUNDRO: http://selfawaresystems.files.wordpress.com/2008/01/ai_drive...
I urge you to read it. It really is a wonderful paper.
Most chefs are male - people don't care because its a low status job. Programming is now high status, so now this gender gap is an issue. As many feminists have "misogynistic conspiracy" as their default explanation for any differnces in outcome among genders, they're not in a very good epistemic position to judge these things. Unjust discrimination is economically counterproductive, I don't expect ruthless corporations to support such a conspiracy when defection is more profitable. Aside from blinded applications and maybe interviews, not much needs to be done. We are building businesses here, not collecting data for a census.
What? Was everyone blind before the discovery of quantum mechanics? If we can't measure things we don't understand, how the heck would we come to understand them? Through their affects on the world? "No, you say, "we can not perceive things whose causes we don't understand." Where did you get your epistemology? Was it The Secret?
Slightly-misleading TLDR:
Iterated embryo selection is sort of test tube reproduction and selectiong. If you can create gametes from stem cells, then create many more embryos with these gametes and then score each embryo, repeating the process selecting for those that have the best genetic correlates of cognitive ability, you can perform the equivalent of a 2000 year eugenics experiment in a test tube in about six months. You could potentially get far, far higher IQs than 160.
Prerequisites for this are cheap-gene sequencing, very, very large databases of genomes tagged with their donor’s cognitive measures, and advances in human stem cell research.
This is indisputable. Denying IQ and its heritability is equivalent to denying global warming. It’s settled science. Dysgenics is certainly possible. I think technology like iterated embryo selection and genetic engineering will come into common use before dysgenics kicks in. China is already investigating these possibilities, and their culture does not have the same memetic immune response to such ideas. After one country makes it legal, competitive pressures will force the rest of the world to do it, too. Iterated embryo selection could conservatively raise IQ by 60 points, likely much much more: http://www.nickbostrom.com/papers/embryo.pdf
A government would have to be supernaturally incompetent to allow such a gap to develop.
You've got this normative halo around "intelligence". All intelligence is, is an agent's ability to satisfy its utility function.
>But if it continues to work on the paper clips and decides that they are still needed even after people are gone - how is that super intelligent?
That is the correct action if all it cares about is making paperclips. Creating paperclips satisfies its utility function. Fretting over the existential issues of creating paperclips long after the last piece of stationary was destroyed would be judged of negative utility.
