  • 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.






  • Yes. Because an infinitesimally small number of business owners say so, all business owners must.

    There’s over 4.2 million small businesses in CA alone.

    Most of which are owned and operated by totally normal, not-awful people.

    I can’t know their politics and neither can you.

    What I can tell you is that cities across the country are fucking up the crisis and leaving everyone else involved in a lurch. The homeless people themselves are the most obvious and most needy, don’t get me wrong.

    But the current situation is also impacting businesses, causing them to either move away or close as people stop shopping.

    City and state governments are fucking it up. Not the fucking barber who probably is a member of that community just trying to earn a living. Not the others who had already left or closed and were also part of the community, probably.




  • and the business is the one deciding these things?

    Like. I get it.

    The way we treat homeless people sucks in this country.

    It shouldn’t be that way. But the business isn’t the one setting those policies here. That’s on LA and the CA governments. And while yes, some of the business interests are voicing opinions here… the barber shop and the landlords here aren’t big enough to have any pull. Many are just looking for ways to end it… and would fully support doing housing-first strategies and all that. (because they work.)




  • so by way of examples, going to some extremes…

    Kent County, Texas is one of the most rural counties in the US. with Jayton hosting its county court house. As of the 2020 census, the entire county has less than one thousand people. The terms small town/town are somewhat nebulous, But usually in really rural places it’s someplace with a few shops and maybe a neighborhood and school and stuff.

    This is a sat photo of Jayton, compliments of google maps:

    Jayton has about 500 people.

    Note, that the mile is about 1.25 miles/ 2 km’s north to south and about the same in east west. (at least, as far the structures/housing goes.) to get an idea of what it looks like there, here’s the streetview in front of the court house.

    zooming out to kent county, there’s like 5 towns in that entire square, note the distance marker down at the bottom being about 8 km:

    now, compare that to new york city:

    Note, the distance marker at the bottom being about 3 km.

    zooming in to roughly the same scale as the photo on jayton… randomly…

    and here’s a few courthouses in brooklyn…

    and the king’s county courthouse on streetview

    <chuckles on linux> “he doesn’t know how to use the middle mouse button!”

    (for people who may be unaware… in most linux distributions- all of them that I’ve used, and I’ve used a fair number; clicking middle mouse with text selected cuts and pastes the text. it’s one of those features that, once you get used to… you just can’t let go.)
