    I know it’s a shitpost, but i hate that people interpret carcinisation as a crab being the ultimate piece of evolution.

    When learning evolution like algorithms in computer science, one of the first things you learn is strategies to not get stuck in locally optimal solutions (solutions that seem the best when you look at other nearby solutions, but are worse than other solutions if you allow your algorithm to look further away).

    Crabs seem like that, it’s just an easy defensive evolution that then stagnates in a form that kind of works. Seeing how many crabs we eat, and how few crabs eat us, it’s obvious that crabs aren’t the actual pinnacle of evolution, just some locally optimal solution that evolution tends to get stuck in :p.

      After several days of what I can only describe as ill-informed pro crab propaganda posts all over lemmy I realy needed this. Thank you.

      I understand your point but some of history’s most well known and powerful figures have been consumed by crabs. Amelia Earhart and countless other well known examples through history show the crab threat is much more present and real than you imply.

    Train cars are crabs. They’ve got an exoskeleton, they’re squat bodied, many legged, and have pincers on either side. All they have to do is start moving that body plan around some and they will be crabs.

      Checks out: while they CAN move forward, they highly prefer to move side to side

    the Dutch train system is so incredibly cool, you can get from one end to another end of the ‘main’ part of the Netherlands in an hour and its so easy to just get to any station anywhere and then you can just go everywhere for so incredibly cheap. Literally the only thing you need to get anywhere in the Netherlands is a bike and something to buy train tickets with. You dont even need to buy tickets, you can just tap your debit card on the gates in the entrance station and then tap it when you exit and it just handles everything for you

      you can even tap on sone bikes to rent them. everyone saying owning a car makes you free can suck it

    Why does Lemmy and reddit love trains so much? They could solve some travel problems in some but are we expecting tracks to run literally everywhere and into every suburb? What about rural places?

    “we heavily biased the network against trains and now it’s just saying the optimal car consists of several metal struts connecting just two thinned out wheels that the driver sits on top of and propels themselves using pedals. It was busy redesigning intersections to have clear safe lanes for these bi-cycle ‘cars’ with plenty of trees / room for pedestrians when we pulled the plug…”

      Even in bike racing the optimal form ends being to become a train. A peloton is just a train made up of bikes.

        And then imagine if instead of wheels a bicycle was on a track with even greater reduced rolling resistance than skinny overinflated tires and didn’t require lumbar strength for balance.

    Ha! I was thinking along these lines reading science fiction the other day. In every novel where stuff has to get moved overland, it’s always a train. No matter their tech level, trains are the simplest, most efficient solution.

    I also really like that every time I see some dumb idea to “improve vehicles” there a long comment chain improving it even further into a train.

      Hey there 👋, I know you mean well by that comment, like I get it, I do. ☺️ But I just wanted to let you know:

      THERE HAVE BEEN ZERO STUDIES DONE ON THE SAFETY OF CRAB TRAINS.

      ZERO.

      But despite that, they are gaining widespread support, and now even people like yourself are calling them “optimal.”

      Listen: Someone I know lost an arm in the pincer mechanism of one of these trains. More work needs to be done before we can consider them safe, nevermind “optimal”. Don’t buy into the techbro BS.

      Friends don’t let friends crab train.
