orbifold··on Class switch towards non-inflammatory IgG4 antibodies after vaccination
Ok, well then it might turn out that some of the fringe scientists were right all along. A healthy young male like me would probably have been far better off to not receive any kind of vaccine, I only got Covid after a third booster and I don’t think I could have had it any worse.
orbifold··on JFK Assassination Records – 2022 Additional Documents Release
I read this differently, it should have put whatever you said in quotation marks, but it clearly is just saying that it doesn't know and therefore you might be right.
orbifold··on Who knew the first AI battles would be fought by artists?
Ok, let me try to be technical. These models fundamentally can be understood as containing a parametrised model of an intractable probability distribution ("human created images", "human created text"), which can be conditioned on a user provided input ("show me three cats doing a tango", "give me a summary of the main achievements of Richard Feynman") and sampled from. The way they achieve their impressive performance is by being exposed to as much of human created content as possible, once that has happened they have limited to no ways of self-improvement.

I disagree that there is no originality in art styles, human creativity amounts to more than just copying other people. There is no way a current gen AI model would be able to create truly original mathematics or physics, it is just able to reproduce facsimile and convincing bullshit that looks like it. Before long the models will probably able to do formal reasoning in a system like Lean 4, but that is a long way of from truly inventive mathematics or physics.

Art is more subtle, but what these models produce is mostly "kitsch". It is telling that their idea of "aesthetics" involves anime fan art and other commercial work. Anyways, I don't like the commercial aspects of copyright all that much, but what I like is humans over machines. I believe in freely reusing and building on the work of others, but not on machines doing the same. Our interests are simply not aligned at this point.

orbifold··on Who knew the first AI battles would be fought by artists?
There is a significant contingent of influential people that disagree. "Why the future doesn't need us" (https://www.wired.com/2000/04/joy-2/), Ray Kurzweil etc. This is qualitatively different than what the Luddites faced, it concerns all of us and touches the essence of what makes us human. This isn't the kind of technology that has the potential to make our lives better in the long run, it will almost surely be used for more harm than good. Not only are these models trained on the collectively created output of humanity, the key application areas are to subjugate, control and manipulate us. I agree with you that this will not happen immediately, because of the very real complexities of physical manufacturing, but if this part of the process isn't stopped in its tracks, the resulting progress is unlikely to be curtailed. I at least fundamentally think that the use of all of our data and output to train these models is unethical, especially if the output is not freely shared and made available.
orbifold··on Who knew the first AI battles would be fought by artists?
I think this drastically overestimates what current AI algorithms are actually capable of, there is little to no hint of genuine creativity in them. They are currently severely limited by the amount of high quality training data not the model size. They are really mostly copying whatever they were trained on, but on a scale that it appears indistinguishable from intelligent creation. As humans we don't have to agree that our collective creative output can be harvested and used to train our replacements. The benefits of allowing this will be had by a very small group of corporations and individuals, while everyone else will lose out if this continues as is. This will and can turn into an existential threat to humanity, so it is different from workers destroying mechanical looms during the industrial revolution. Our existence is at stake here.
orbifold··on Ask HN: Getting into AI?
To clarify the link I posted above, was for a job opening not in our group but in the group of Jörg Conradt, I think he would be happy if you send him a mail. I'm at a physics institute, so it is hard to hire non-physicists. I'm trying to be semi-anonymous here so I would prefer to not share my mail, but I can reach out to you if you give me a way to contact you.
orbifold··on Ask HN: Getting into AI?
There is no expectation that you have published, you would be evaluated based on your academic record but also your industry experience. I can’t tell you how things work in the case of Industry PhD, but I can definitely tell you that since now a lot of academic fields have connections to AI and could really use people with strong engineering skills, there is a good chance you could find such a position.
orbifold··on Ask HN: Getting into AI?
You can do a PhD in the field, depending on your background this wouldn’t necessarily mean that you had to give up working. There are many companies interested in „Industry PhD“ and your experience and background in robotics would probably be a great fit at many places. To give you an example I recently interacted with someone that was doing a PhD and was working for Stabilo (a German pen maker).

Here is a random PhD job opening in Stockholm, that I just got send. I know the professor he would be very happy if someone with industry experience showed up:

We have a PhD opening in my group, addressing “event-based vision in challenging automotive environments”. https://kth.varbi.com/en/what:job/jobID:560761/type:job/wher...

orbifold··on Why doesn't Arnold Schwarznegger show up in this query on Google?
Definitely somewhat racist.
orbifold··on Europe accuses US of profiting from war
The US was the one that doing the meddling primarily, they used the EU as one of the carrots. Victoria Newland famously was recorded saying “fuck the EU”. Germany for example deliberately moved to cut out Ukraine as a transfer country for their gas supply by going for Nordstream 1&2. One reason was that Ukraine tried to use that dependence as leverage on multiple occasions. It is a long and complicated story starting sometime after the collapse of the Soviet Union but in many ways even connected to WW1. I feel sympathy for the Russian and Ukrainian people, that they had consistently some of the worst politicians and rulers imaginable.
orbifold··on Europe accuses US of profiting from war
We would have done Ukraine a huge favor if we hadn’t involved ourselves in their internal politics at all. No funding of NGOs, no attempts to integrate them in EU or NATO. It is too late now, but the way that this had become a literal cottage industry of Ukraine think tanks even before this year, all the way back to the “Orange revolution”, did never correspond to the enthusiasm the average European have for Ukraine.
orbifold··on An autistic man was surfing the internet on his dad’s sofa, then the FBI arrived
So do people with autism automatically have some form of anti-social personality disorder? If someone doesn't have empathy or can understand how they are hurting others that should be cause for a lot of concern.
orbifold··on Galactica: an AI trained on humanity's scientific knowledge (by Meta)
The reply to the prompt is almost complete non-sense. In particular the statements about the speed of sound in vacuum. However in some instances (synthetic quantum systems) you can treat the speed of sound in an ultra-cold gas as the „light-speed“ in a curved space-time. This was recently experimentally demonstrated.

I think in the future humans will need to invent secret languages, not digitized or shared with computers in order to be able to filter wrong but convincing information.

orbifold··on Galactica: an AI trained on humanity's scientific knowledge (by Meta)
I tried it on two topics I am a domain expert in both in the suggested „lecture notes on …“. It produced rethorically nice sounding sentences with little actual content, that quickly desolved into non-sense. I guess to an outside observer that might appear similar to what happens in academia often :):
orbifold··on The most unethical thing I was asked to build while working at Twitter in 2015
You can and there were / are 7-8 Hubble sized telescopes in orbit, with somewhat other optics and sensors looking in the other direction. Most likely the same is true for siblings of JWT.
orbifold··on Sile: A Modern Rewrite of TeX
I've never attempted to change the layout substantially except for using different document classes. I just hand off the manuscript at some point to professional editors and type setters at an academic publisher and they do their thing. It still beats everything else as an authoring tool and source for professionals to start working from.
orbifold··on Applied category theory in chemistry, computing, and social networks [pdf]
To properly talk about compositionality in differential equations you absolutely need category theory. Likewise I firmly believe that PDE and numerical mathematics actually lack a good foundation in category theory, not that they don’t need one.

It is just very hard to create non-trivial general theories in sich „Applied“ fields, Functional Analysis alone is not very exciting. For an example see for example the work or Hairer (stochastic differential equations) or Costello (QFT).

orbifold··on Nanowire synapses 30,000x faster than nature’s
Short answer is no. The field is full with tenuous analogies. Then again „Neural Networks“ are also at best metaphorically related. More accurate existing Neuron models are actually also plagued by lots of limitations among them that they are typically implemented in 3 ancient domain specific languages with lots and lots of hardcoded constants copied from research papers.
orbifold··on Feynman’s Breakthrough: Disregard Others
One thing that can paralise you as a researcher is to be too concerned with what others are doing, that is for sure. Some journals even discourage or eliminate claims of priority (eg Phys Rev). The time you spend worrying about the work of others could be more productively spend expressing your ideas.
orbifold··on Princeton lab simulates nuclear war (2019)
The publicly known US tests of hypersonic gliders all failed or rather disintegrated, as I said there is a genuinely hard problem to be solved here and the US stopped research into it in the 80s for quite a while.
orbifold··on Princeton lab simulates nuclear war (2019)
Russia has hypersonic reentry vehicles, they are pretty much impossible to intercept (https://en.m.wikipedia.org/wiki/RS-28_Sarmat), each of these MIRV contains 10-15 nuclear warheads or an unspecified number of hypersonic glide vehicles (https://en.m.wikipedia.org/wiki/Avangard_(hypersonic_glide_v... )with nuclear payloads. They figured out the hydrodynamics to make the hypersonic glide vehicles work, I believe the US is roughly a decade behind on that. Note that this requires genuinely hard math to do and the US funding on this was temporarily suspended because it was thought to be infeasible.
orbifold··on Stability.ai sent a take down request to Runway ML's SD v1.5 citing IP Leak
It seems very weird to me that “stability” is building a company around something they didn’t create.
orbifold··on Drone footage reveals The Line megacity under construction in Saudi Arabia
If you go far back enough the Romans were responsible for founding a large number of modern day Western European cities. In CIV terms building a city surrounded by desert tiles is just a very late game move.
orbifold··on Heart risks, data gaps fuel debate over Covid-19 boosters for young people
The chance of healthy young males dying from Covid is close to zero and not 0.3%. I recently had Covid, less than 6 months after the booster and I don’t think it could have been worse than it was. The third shot measurably impacted my fitness metrics, according do my Apple Watch (sharp decline in VO2max, which took months to recover and even pre Covid it was 3 points off)
orbifold··on Heart risks, data gaps fuel debate over Covid-19 boosters for young people
There was a messaging lag between countries. You could discern pretty clearly what was doing to happen from whatever happened in Israel as they were roughly half a year ahead and almost simultaneously vaccinated everyone. Based on what happened there with both the initial vaccine and the boosters, you could tell that your local politicians, media and experts where lying and or obfuscating and misrepresenting facts.
orbifold··on AI Data Laundering
These articles use far more cautious language than you suggest and if they don't everyone working in the field is hopefully aware that such claims are the academic equivalent of clickbait at best.
orbifold··on Software, not hardware, will drive quantum and neuromorphic computing
I agree and that is why we have build Norse https://github.com/norse/norse an open source deep learning library for neuromorphic computing based on PyTorch. It doesn’t have any commercial backing yet, but we had quite a bit of interest in from other research groups and it predates Lava by quite a bit .
orbifold··on I've said it all before but here we go again
It is hard to use twitter and not be drawn into negativity and conflict. I think that is mainly because it not only recommends tweets by people you follow. You quickly end up getting exposed to lots of content other people „liked“. Which more often than not is written by people with several mental illnesses, people in tough financial or social situations or successes like Nature papers, Conference acceptances and so on. There is very little room for „normal content“.

I’ve managed to promote one of my articles successfully there with ~1 million impressions, but otherwise using the platform has been a net negative.

who are they and how do you get in?
orbifold··on What's SAP, and why's it worth $163B? (2020)
Golf is really the key here, much nicer to play a few rounds of golf with Dietmar in his Club than think too hard about ERP processes.
