<p>With the old way of doing things you could spend energy to reduce errors, and balance that against the entropy of you environment/new features/whatever at a rate appropriate for your problem.<p>It's not obvious if that's the case with llm based development. Of course you could 'use llms until things get crazy then stop' but that doesn't seem part of the zeitgeist.</p>

<p>Another interesting thing about the steam engine is much of science in the 1800s was dedicated to figuring out how steam engines actually worked to improve their efficiency. That may be similar for AI, or it may not!</p>

<p>We made an AlphaGo like implementation for the card game Dominion. Certainly not the same number of cards but similar complexity. I have high confidence the same techniques would work for mtg. In fact possibly better as mtg doesn't lend to large search depths. Though possibly worse as there is more hidden information (though that depends on if the format has open deck lists and/or how much of the meta is provided to or trained by the nn)</p>

For over a century, there were a group of people working on building, maintaining, repairing, refining and improving engines, called 'engineers', who had a very incomplete picture of the physical laws surrounding them. I would assume there were many explosions and other accidents along the way (as there continue to be).<p>The investment in the science of thermodynamics and the chemistry of fuels was largely motivated by the value of the steam engine, and the attempts to improve efficiencies allowing miniaturization, enabling locomotives and the railroad boom, and eventually automobiles and powered flight.<p>I think the era from say 1950..2020 has been a relatively unique period in history where science has been ahead of praxis (though folks in medicine or other fields might not have had that luxury). Recent advancements in AI preceding strong theoretical foundations might be a reversion to the mean.</p>

<p>And in fact, the first engines were developed without a robust understanding of the physics behind them. So, the original version of 'engineering' is more closely to the current practices surrounding AI than the modern reinterpretation the root comment demands.</p>

<p>Seems like it'd be relatively easy  to allow one to 'smooth' their income over multiple years. Imagine paying 100 income at 40% tax year 1 and 0 income year 2. A scheme where you could retcon things to be 50, 50, each at say 30% for a 10k refund (or at least credit) seems very doable.</p>

<p>I don't understand how inflation and risk wouldn't/aren't priced in. You have $1000. You can: put it in your mattress, put it in 'safe' treasury bonds at inflation +a few percent, or yolo it in NVIDIA. Yes if bonds are returning less than inflation you don't buy them and that makes financing more expensive   but it's not somehow unfair vs the other things you could do with capital.<p>Seems like return is roughly proportional to risk<i>(1-tax)</i>investment so changing tax should affect everything proportionally (barring cheating/avoiding the system in some way).</p>

<p>The similarity between divine right of kings and inheritance is that an unearned is transferred via circumstances of birth.<p>Your statements seem to extend that further: If you rent an apartment, you the property is owned by an landlord (lord is literally in the title!) and passed down by their wishes. Similarly if you work for Walmart for life, the company is owned and passed down by the Waltons. In these cases the property rights extend beyond life and are transferred via circumstances of birth, while the rights of labor end.<p>Interesting that IP rights are ended by death (or death+n years) as well. This line of reasoning suggests maybe that should apply to all property.</p>

<p>There's no inherent right to anything, really. The statements in whatever declaration or philosophy are just arbitrary lines. Physical property rights are just as arbitrary as the divine right if kings (and incredibly closely related when that property is inherited!)<p>The argument really isn't based on rights, it's based on the rules of the game have been that people that make things get to decide what folks get to do with those things via licensing agreements, except for a very small set of carve outs that everyone knew about when they made the thing. The argument is consent. The counter argument is one/all of ai training falls under one of those carve outs, and/or it's undefined so it should default to whatever anyone wants, and/or we should pass laws that change the rules. Most of these are just as logical as if someone invented resurrection tomorrow, then murder would no longer be a crime.</p>

<p>In a classical view of 2 particles accelerating towards each other v x r will always be 0 so B will always be 0 even if the particles are accelerating towards each other. I believe all this holds under QFT [1].<p>Looking further a redefinition E is necessary when including the \beta factor [2]. So that was a mistake on my part - relativity does change the rhs of Coulomb's law.<p>Admittedly the problem as stated (two particles falling towards each other) constrains things in such a way that there is no off-axis contribution. Or to put it another way, 1d electromagnetism doesn't have magnetism.<p>[1] <a href="https://physics.stackexchange.com/questions/142159/deriving-the-coulomb-force-equation-from-the-idea-of-virtual-photon-exchange" rel="nofollow">https://physics.stackexchange.com/questions/142159/deriving-...</a><p>[2] <a href="https://en.wikipedia.org/wiki/Coulomb%27s_law#In_relativity" rel="nofollow">https://en.wikipedia.org/wiki/Coulomb%27s_law#In_relativity</a></p>

<p>> You can't just plug numbers into Coulomb's Law for this case, because Coulomb's Law by itself is not relativistically correct.<p>Sorry if this is a bit pedantic, but as someone trying to study this at the moment, I don't see this the same way and I'd like to validate my interpretation: You can just plug numbers into Coulomb's law, that part is correct. But then the problem of infinite velocities comes from interpreting the 'F' side of the equation, assuming Newton's law (F=ma), rather than using its relativistic counterpart.<p>Coulomb's law:
F = qq'/r^2<p>Lorentz force law:
F = q(E + mu x B)<p>For the 2 particle case, both of these say the same thing (substitute into the Lorentz eq E = q'/r^2, B = 0 and you get the same thing).<p>The promotion from non-relativistic to relativistic mechanics is a change of what 'F' means.<p>nonrelativistically: F = p' = m v' = m x'' = m a<p>relativistically: F = p' = \gamma m v' = \gamma m x'' = \gamma m a<p>where \gamma is the Lorentz factor.<p>Interpreted this way, infinite velocities are avoided.<p>But, as r->0 we still have an infinity problem - namely infinite energy! This necessitates a quantum mechanical correction to both the Coloumb and Lorentz laws.<p>TLDR: relativity is necessary when things start to move 'very fast', qm is necessary when things are 'very small'</p>

<p>Appreciate your engagement.<p>I think it very much depends on your situation.

<p>Her credentials are her ability to rally support/interest in climate issues. What credentials would satisfy you? Folks with PhDs and political accolades have been speaking the same points for years, and clearly they haven't bread success.<p>Frankly a question to ask is why you feel a person like her isn't encouraged to speak out on these issues, and isn't worth listening to? Is she saying things that aren't true? If so it seems like the thing to do would be to speak to those misstatements.<p>Much more likely though, systemic sexism and ageism make it difficult for folks to accept young women in leadership roles, particularly when their message asks for change from the status quo.<p>So the reasons you should care about what this person is saying are 1) she is speaking truths about climate change 2) the truths are about existential threats to humanity and she is able to communicate the seriousness of those threats 3) she is able to rally groups of like minded people with a common vision of those threats and their seriousness 4) paying attention to her and uplifting her leadership role helps erode systemic sexism and ageism.</p>

<p>Yeah, if you could input data set X with quality Q(X) and output data set Y of the same size with Q(Y) > Q(X), you'd really be on to something. But I don't think such a system exists yet, or even close. Inputting the internet, outputting a sea of garbage with a handful of diamonds that people have to spelunk through the garbage for seems the best so far. Madlibs is a pretty equivalent activity, and while fun, certainly not anything one would consider AGI. We need a revolutionary improvement on automated spelunking to get anywhere. Maybe we'll get a good spam filter as a side effect!<p>But even if you had a system, there's still the resource cost to run the algorithm (needs to be bounded or else you've just made a finite jump) and the gains you make need to not decay (or again you've just made a finite jump).<p>And all this needs to be compared against investing in humans - which seem pretty clearly to have AGI properties (but with some really bad constant factors. 20 year training time - ridiculous!)<p>To me it seems things are a long way off and least a couple of major innovations away. But at least there's some ideas of the problems to tackle, which is a big step up!</p>
