<p>The "AI" does not give "financial advice". It autocompletes your prompt. If you provide the right context and ask the right questions you will get the most likely consensus on such a widely discussed topic.</p>

<p>It turns out LDL has different subfractions based on size. Normally, the liver produces large ones which shuttle fat around the bloodstream, lose their payload and shrink then the liver reabsorbs them and the cycle continues.<p>The problem appears to begin when these LDL molecules hang around for too long. They are damaged by external factors in the bloodstream (eg. glycation due to high blood glucose, oxidation due to fragile polyunsaturated fats) and not recognized anymore for recycling. That's when they can start forming macrophages.<p>tl;dr LDL by itself is an incorrect measure of cardiovascular risk. Big pharma still profits by selling everyone LDL reducing drugs.<p>one authentic source: <a href="https://www.youtube.com/watch?v=fVLZA0qp-wc" rel="nofollow">https://www.youtube.com/watch?v=fVLZA0qp-wc</a></p>

<p>Mathematics is a language. If anything, it's much more well defined and formal than most others. Train on enough examples and statistical autocomplete gets you places. I'm surprised how anyone would even consider this intelligence?</p>

<p>I hold my stance that LLMs are stochastic parrots.<p>Making the parrots ever more complex and training on ever more data produced by intelligent, creative beings may make them more useful or convincing but does at no point give rise to intelligence or creativity.</p>

<p>Similar to your contractor example, I like to think of the useful way to use LLMs as doing "grep -C" (show lines surrounding the match).<p>You provide some context you are looking to expand on and let the LLM autocomplete provide you with relevant terms and concepts that have historically come up in that context and may or may not be actually useful. Then you do due diligence to learn about those related concepts, determine their applicability and distill it all down into a solution.</p>

<p>It will be interesting to see when ads and propaganda are seamlessly (but purposefully) integrated into the output of LLMs. Who will decide what you should want or think? Will you even notice?<p>As for now, autocomplete is only as good as the training data. Once humanity collectively stop being autonomous beings and generating novel ideas, it all comes to a halt. LLM suggested ideas and preferences are nothing more than some mashup/average of what came before. The ability to actually think may become a rare treasure.</p>

<p>Just a reminder: LLMs are statistical models that predict the next token based on preceeding tokens. They have no feelings, goals, relationships, life experience, understanding of the human condition and so on. Treat them accordingly.</p>

<p>I don't think using git should necessarily be taught as a part of a CS education. Any self respecting engineer will be capable and have the curiosity and motivation to dig into it on their own. CS should give them the prereqs to do so, such as hashing, graphs, trees, etc.</p>

<p>If the fields of a structure or the string keys of an untyped map don't match then you don't have compatibility either way. The same is not true for restricting the set of valid values.<p>edit: To put it differently: To possibly be compatible with the nested "Circle" map, you need to know it is supposed to have a "Radius" key that is supposed to be a float. Type definitions just make this explicit. But just because your "Radius" can't be 0, you shouldn't make it incompatible with everything else operating on floats in general.</p>

<p>Every time you introduce a type for a "value invariant" you lose compatibility and force others to make cumbersome type conversions.<p>To me, invalid values are best expressed with optional error returns along with the value that are part of the function signature. Types are best used to only encode information about the hierarchy of structures composed of primitive types. They help define and navigate the representation of composite things as opposed to just having dynamic nested maps of arbitrary strings.</p>
