<p>The challenges you mentioned, and techniques to address them, are not unique to quantum physics.  I am still not understanding how quantum physics require "new" kind of numerical analysis.  And what are these new kinds of techniques you hint at?  Could you give me some examples of unique techniques that arose from quantum physics and are not used elsewhere?</p>

<p>> when I can get away with it I'd prefer to prove things with real numbers and assume magically they transfer to floating point.<p>True for some approaches, but numerical analysis does account for machine epsilon and truncation errors.<p>I am aware that Inria works with Coq as your link shows.  However, the link itself does not answer my question.  As a concrete example, how would you prove an implementation of a Kalman filter is correct?</p>

<p>During the days I was studying/working with Coq, one visiting professor gave a presentation on defense software design.  An example presented was control logic for F-16, which the professor presumably worked on.  A student asked how do you prove "correctness", i.e. operability, of a jet fighter and its control logic?  I don't think the professor had a satisfying answer.<p>My question is the same, albeit more technically refined.  How do you prove the correctness of a numerical algorithm (operating on a quantized continuum) using type-theoretic/category-theoretic tools like theorem provers like Coq?  There are documented tragedies where numerical rounding error of the control logic of a missile costed lives.  I have proved mathematical theorems before (Curry-Howard!) but they were mathematical object driven (e.g. sets, groups) not continuous numbers.</p>

<p>This paper reminds me of a class assignment in grad school where the prof asked the students to write a compiler in Coq for some toy Turning-complete language in a week.  Having no background in compiler design or functional programming, I found it daunting at first, but eventually managed it.  The Coq language's rigor really helps with something like this.<p>I wonder if AI's compute graph would benefit from a language-level rigor as of Coq.</p>

<p>> Job losses could shave 30 cents off each item purchased by 2027.<p>This is incredible.  It's far less than I would imagine.  It represents how well optimized the warehouses are.  If we roughly estimate a median product price to be $20, then the automation represents less than 2% cost saving.  Of course, Amazon is at a scale that this is still net positive despite all the R&D cost.  But if automation was to reduce the cost of living, there are probably better areas to focus on.</p>

<p>What a great project.<p>What's interesting is that action tokens are learned from video.  In other words, the training dataset does not include actions like "go left" and "go right"; and these actions are learned from the pixels that moved.  This means that learned actions may not map exactly to the game actions available to the user.  That means we (humans) cannot necessarily use this world model to play the game.<p>I suspect the inferred actions probably directly correspond to human-understandable actions; and after playing with the action tokens, a reasonable human can probably guess what, say, the third action token in the dictionary corresponds to ("jump").  This is likely as game actions are sparse (in both time and action spaces) and often independent/orthogonal (in action space).</p>

<p>I had a colleague, an architect deeply soaked in the Design Thinking cool aid, telling me that architecting a single-family house is humankind's most intellectually challenging endeavor because he has to worry about the end users and construction materials that go in ("holistic[TM]").  I asked him if building a space shuttle is easier than building a house, and he genuinely believed that engineers have a far easier (and dumber) time than designers like himself.<p>This take of designers being superior being to engineers is something I consistently observed among designers over the decade.<p>Here is a light-hearted video:

<p>I would like to see evidence behind this claim on two fronts:
1. <i>all</i> parts are produced in other countries
2. <i>slightly</i> higher prices<p>There are countries (including Ukraine) that produce on-board flight controllers, but the controllers themselves often rely on components from China.  I actually do think it is feasible to create a passable quadrotor using non-Chinese components only but I do not know of a rigorous study or a manufacturer that does this.</p>

<p>> Today, engineers working on AI systems also need to think deeply and critically about the relationship between language and culture and the history and philosophy of technology. When they fail to do so, their systems literally start to break down.<p>Perhaps so.  But not in the (quasi-)academic sense that the author is thinking. It's not the lack of an engineer's academic knowledge in history and philosophy that makes an AI system fail.<p>> Then there’s the newfound ability of non-technical people in the humanities to write their own code. This is a bigger deal than many in my field seem to recognize. I suspect this will change soon. The emerging generation of historians will simply take it for granted that they can create their own custom research and teaching tools and deploy them at will, more or less for free.<p>This is the lede buried deep inside the article.  When the basic coding skill (or any skill) is commoditized, it's the people with complementary skills that benefit the most.</p>
