  • The problem comes in, what happens when a heart fails? depending on the failure mode, it may represent a total blockage, in which case you’re toast. You might be able to survive with one heart if you had two, but if you add a second heart, then your other heart will likely be less developed unable to perform at whatever peak performance you had before.

    If your method of redundancy adds more single points of failures. Also, the addition of a second heart poses the problem of keeping them coordinated; with all sorts of problems coming up if they get out of sync. adding redundancy will always add complexity, especially as you work to remove single points of failure and try not to add extra. In some systems, it’s just unwise to add redundency because the complexity means it’s more likely to fail.

    Famously, Charles Lindbergh, for example, opted for a single reliable engine over two engines. It kinda flew in the face at the time. But then he was the first to go from NY to Paris in a non stop flight, in the Spirit of St Louis. Similarly, we can expect, if there was in fact some significant advantage, that then, everybody would be doing it. Or, at least, lots.

    Keep in mind, cephalopods have 3 hearts- 2 are single chamgered things that boost blood over gills, and the 3rd provides bloodflow to the rest of the body. Hagfish have one chambered heart and several boster things that aren’t really much of a heart. Earthworms aren’t possessed of true hearts (they lack chambers and valves,) cochroaches and leaches also don’t have true hearts.

    But where we see 4 chambered hearts (birds, mammals, and crocodillian reptiles,) they all only have 1. That should tell you something.

    Is there a larger point I’m missing?

    yeah there is.

    Einstein gained his prominence by demonstrating the validity of his theory of general relativity; and the experiments surrounding it panning out. He faced criticism from many colleagues- many of whom detracted from his work by pointing at the mathematical and abstract nature of it and preferring experimental evidence.

    You’ll note that those critic’s competing theories have fallen by the wayside as experimental evidence came in demonstrating Einstein’s theory to be the more correct one.

    He also faced a shitload of antisemitism, with many critics calling him a fraud and a plagiarist, questioning the validity of his work simply because he was a jew.

    You’ll also note that Einstein grew up poor, in Germany, and during the early stages of his career faced the rampant antisemitism of the weinmar republic. During which time he did in fact earn a nobel prize. As we come up to the time in which he fled the fucking nazis who siezed, they stole all of his assets, burned his books and he barely got out alive. Even then in the US he faced antisemitism here, despite already being world famous for his ideas, thoughts and keen intellect.

    Musk, on the other hand is a south african aparthied neppo baby. at no point was he ever “poor”. that’s all bullshit. He got his wealth from his father’s emerald mine in Zambia. The conditions in that mine were straight up horrific, but don’t let that bother you. I’m sure Elon is really a great dude. (bleck.)

    At no point was Musk ever fleeing anyone only to face more of the same in Canada or the US. He lied to retain his academic visa depsite dropping out and should have been deported, but alas, Neppo Babies get special exemptions.

    To compare Musk to Einstein is patently ridiculous. Musk is an utter fucking moron with the soul of a ghoul. The conditions at his companies are horrific by US standards with safety only a consideration insofar as it’s regulatorily mandated, and even then often ignored. Trade advocates along side actual experts were always among the first to be his critics.

    of his most successful “ventures” Paypal only took off after they shitcanned him for being a terrible boss. In fact Paypal acquired his financial services software and that’s how he’s associated with Paypal at all. it wasn’t his baby.

    Tesla and space x are only viable because they’re welfare queens. If you account for the shitloads of government subsidies they’re given in their earnings, you’d see that they’re not in fact successful companies.

    You also know that musk is not, has never been, universally lauded as anything but a raging narcissist.
    

    Seems like wishful thinking or at least gaslighting.

    You’re an utter fucking moron if you think that’s gaslighting. read the statement again. has musk been lauded as a genius? yes. But far from universally so. He’s going to go down in history as yet another dumbass nazis. that’s his legacy.

    but why take my word for it.

    Hyperloop, for example is replete with examples of his stupidity. So much so that it was initially questioned. initially the reviews were simply skeptical- especially focussing on the cost. then as more details of how it would work came out, that skepticism turned to rampant derision. (1, 2)

    here’s some more scathing reviews; 1, 2,

    the Boring Company, too. When hyperloop faile,d he doubled down on that, and that was laughably stupid. So much so I’m just gonna let you go have fun researching on your own. (try google.)

    It is patently offensive that you compare the two. One is a man who fled from nazis and built his reputation by doing credible research and expanding our understanding of the universe around us by leaps and bounds and the other is a dumbass nazis wellfare queen who relies on rubes to silence any criticism. The two stories aren’t even close to the same.


  • You know there were plenty of American Nazis in Einstein’s time, right?

    You also know that musk is not, has never been, universally lauded as anything but a raging narcissist.

    In fact, quite unlike Einstein, everybody who was an engineer or whatever and worked with him all hated his guts and have been saying this entire time that he’s 1) stupid and 2) awful.

    The only people saying that Musk was anything but stupid were either his PR team, or the dupes that bought their hype.
