<p>So, this question occurred to me after watching these two videos in quick succession and then doing some additional lit search, I apologize if my terminology is imprecise/inaccurate since this isn't my field but hopefully I can communicate my meaning here:<p>https://www.youtube.com/watch?v=Jm7omDy5_38<p>https://www.youtube.com/watch?v=EK32jo7i5LQ<p>We just learned that our models of galactic evolution were incorrect due to data from the JWST, and we currently don't know why galaxies form into spirals. What if galaxies actually just tend towards this shape over time because they are actually approaching exactly this distribution of the prime numbers when mapped onto polar coordinates? It even makes sense; every star has a gravitational influence on every other star in the galaxy, you would expect that their orbits would be influenced by resonance, they would naturally distribute based on approximating the distribution of the prime numbers which is necessarily the most chaotic pattern/the orientation with the highest entropy. Perhaps galaxies form spirals simply because they are following the 2nd law of thermodynamics, and the fact that you see four-armed spiral galaxies is exactly because of PNT sorting all the stars into four arms. In which case "dark matter" has actually always just been the 2nd Law. There may even be some relationship to the different spiral and elliptical galaxies we see and the shape of this plot of the prime numbers at different scales: at more "zoomed out" approximations you see a more elliptical shape and at more "zoomed in" approximations you see spirals with arms of different densities.</p>

<p>The degree to which science has advanced since the Webb project started can't be understated either. We have a fundamentally better understanding of the technology available and what we even want to look at. Much better to simply move onto the next project, of which there are currently very many.</p>

<p>We're closer than you'd think. Chlorophyll is only something like 28% efficient at absorbing sunlight, we have experimental solar panels pushing 45%. Collecting wavelengths the plants don't use and then lighting them only in wavelengths they do use has a significant potential for efficiency gains, though we're not quite there yet...</p>

<p>Yes, soil, temperature, and weather control are huge, as is the lack of need for pesticides. Hard to over-state how much controlled environments can improve yields and crop quality and reduce costs of maintenance (in return for large initial capital investment).</p>

<p>This is not a one-in-a-million event, this is not something that no one could've predicted, many people predicted it and we blithely ignored them. This is the direct consequence of our consistent policies and behavior. This is like standing 99 feet from a cliff and saying "well the next 100 feet in front of me is 99% solid ground and 1% air, sounds safe to me!" and then walking right off of the cliff.</p>

<p>> And taking on debt to do it isn't inherently irresponsible. In fact, it's just a wise financial decision when interest rates are low. New revenue streams aren't required to be generated -- it's just shifting a subset of future revenue to the present.<p>I don't know how someone could possibly make this statement RIGHT NOW of all times? How many businesses are sitting on the edge of folding right now? Whoops!  Looks like all that future revenue didn't show up! Guess who's going to suffer for these decisions? Not the investors, they sold out! How about all the employees who just had all the blood sucked out of their job security and future livelihood?<p>In what sense are investors in this scenario not just hostile parasites? At least if it were dividends then the investors would have any sort of remaining long-term interest in the success of the company, and not just how they can most quickly disentangle themselves from taking any responsibility for the survival of the company that they ostensibly had ownership over by gulping down revenue it didn't even generate yet? In what sense is the investor not crippling the company and leaving it weaker than they found it? It's vampirism! Just because the money is there for the taking doesn't mean you should, it doesn't mean that what you're doing isn't irresponsible and even morally reprehensible.<p>You create a nightmarescape of shambling zombie companies just waiting for a global pandemic to remind them that they're all already dead. Enjoy your artificially juiced stock value after it craters because our entire economy is short of legs to stand on.</p>

<p>> If eugenics doesn't work then how come every single Border Collie is smarter than every single English Bulldog?<p>This statement is worse than wrong; it's nonsense.<p>Even if you come up for some very specific metric of intelligence that you think is valid (which will always involve the use of some limited test constrained by subjective considerations) you're still wrong! Not every single Border Collie will perform better than every single English Bulldog, at best you will find some consistent comparison between averages, which is absurdly far from the same thing.</p>

<p>If the company could not possibly get that $1,000 in any other way, then yes the employee is worth $1,000. Without the willing participation of labor, a company cannot produce. If labor is fooled or coerced into working for less than it's worth (say, because otherwise they'll starve or lack health insurance), they are not operating in a free market. They are not getting paid according to their value.</p>

<p>To be fair, all that is really required for human extinction is for us to start firing our nukes. Geopolitically destabilizing events increase the potential for that considerably.<p>That's not in any way to say that climate change must necessarily lead to thermonuclear war or anything so dramatic as that, but human extinction is a real threat hanging over our heads at all times. It's something worth being worried about.</p>

<p>We don't have the luxury of eating the investment on a "dry hole" when this is a global phenomenon. How is the path of highest caution not warranted here? What exactly are we losing by aggressively switching to renewables?<p>This isn't an academic question. It is an incredibly practical one.</p>
