<p>> Soo evolution doesn't always optimize for biochemical efficiency in isolation.<p>How could it?<p>Evolution "optimizes" (as far as local hill climbing can go) <i>fitness</i>, which is the ability to produce viable offspring. Genes get mutated and then combined (in sexual species) and passed to offspring via reproduction ... that's the process that results in biological evolution, which is the change over time of the presence of alleles in a population. That's it -- there's no secret "evolution" sauce or engine. The optimization for fitness occurs through the environment affecting the relative survivability of traits--traits that increase survivability become more common in the population--this part is tautological.</p>

<p>Evolutionary biologists disagree. Adaptations are the result of numerous evolutionary coincidences, but not all evolutionary coincidences are adaptive. Not only are most survivable mutations neutral, but there are traits that are truly "coincidental" in that they come along for the ride, like the color of our blood being red being due to chemistry, not adaptation. (Our visual system that treats red as an alarm, OTOH, is adaptive.)<p>See also <a href="https://en.wikipedia.org/wiki/Genetic_drift" rel="nofollow">https://en.wikipedia.org/wiki/Genetic_drift</a></p>

<p>You complained about the article's talk about "inefficiency" -- you quoted it. But as I noted, THEIR mention of efficiency/inefficiency was ALWAYS about the chemical process, not about efficiency of vision. Now you're totally moving the goalposts. I don't understand why you're playing such an obviously absurd game but I will leave you to it.</p>

<p>A split is a split. Archosaurs split into a crocodile line and a dinosaur/bird line--"the avian lineage" (birds being a kind of dinosaur, and the only ones still living) ... that's what "the avian <i>lineage</i> had split from crocodiles" means -- it is not saying that birds are an offshoot from crocodiles, it's saying that the two lines (both kinds of archosaur) split from each other. Likewise, crocodiles are not an offshoot of dinosaurs.</p>

<p>Note the word "lineage". That would include the dinosaurs that were ancestors of birds. Birds are dinosaurs, so reword the statement as<p>> the dinosaurs had split from crocodiles<p>Birds and crocodiles are both archosaurs (which includes all dinosaurs as well as crocodiles) and are each others' closest living relatives.</p>

<p>Every mention of efficiency is about the chemical process, not about vision as such.<p>> anaerobic glycolysis that is significantly less efficient than oxygen-powered metabolism<p>> Oxygen molecules make energy production in cells extremely efficient.<p>>  the presence of oxygen makes energy extraction from a single glucose molecule 15 times as efficient, and sometimes more.<p>>  This energetic ability is powered by an inefficient metabolism.<p>> This suggested that the strange structure wasn’t bringing oxygen into the bird’s retina; rather, it was helping to pump glucose in, thereby enabling the less efficient anaerobic process.</p>

<p>> My point being - there are two sides to this coin.<p>No, you're simply wrong. UB means that anything can happen. And from a security perspective, that is vital to understand.<p>The only proper response to this code (or similar UB due to ambiguous sequence points) if found in production is to rewrite it and fire or reeducate the author.<p>Sorry, but some people just aren't competent.</p>

<p>Mojo has both Python's def and its own fn -- two different flavors of functions. That alone isn't "cleaner". fn is there for high performance -- it's like Rust added to Python. Mojo is still missing Python functionality because it's early in development, so by that measure it's also not a "cleaner Python" ... and the parts that will never be added are because of performance, not cleanliness. Mojo has never been advertised as a cleaner Python so I don't know what vibes you're going on.<p>This might be helpful: <a href="https://mojolang.org/docs/manual/python-to-mojo/" rel="nofollow">https://mojolang.org/docs/manual/python-to-mojo/</a></p>

<p>Searle's argument may well be about the plausibility of "mechanistic intentionalty", whatever exactly that means ("mechanistic" just sounds like bigotry to me ... we are all mechanisms and Searle didn't say otherwise, just that we are meat mechanisms and not purely syntactic mechanisms ... and his argument was intended as a logical proof, not just a plausibility argument), but that's not what the previous comments were about. Apparently you <i>mechanistically</i> see the word "plausibility" and think that any and all statements about it refer to the same thing.<p>I won't respond further.</p>

<p>Sorry to hear that someone rudely thinks that basic logic is "Nuts".<p>> When that debate is literal (sic) predicated on the assumption that the ability to process language implies consciousness?<p>This is an incoherent claim. Debates are between people with differing claims and often differing assumptions; they aren't "predicated" on some assumption or another--that's a category mistake.<p>Someone can easily argue that LLMs are conscious (or have qualia--that was the disputed claim, and they aren't the same thing) <i>without</i> the strong claim that the ability to process language entails consciousness ... perhaps it is the processing of language together with other features that they think indicates consciousness. For instance, George Lemoine and Richard Dawkins didn't base their judgments on consciousness on such an entailment, but rather on the specifics of what the LLMs said to them.<p>I won't respond about this again.</p>
