  • The definition is that Tesla is shit.

    They’re selling a spotty lane assist as Self Driving when it is not.

    Other companies are selling actual self-driving cars, (even if those companies are fucking up as well) but Tesla is nowhere near that level of autonomy. All because Musk cheaped out on the sensor package.

    Teslas will never be self-driving, because they literally cannot detect the road and obstacles with just their little camera setup.

    They should not be allowed to call it self-driving, or autopilot, or anything else that implies that you can take your hands off the steering wheel.





  • That’s not exactly how it works.

    Most research is based around understanding the universe. Often called Blue Sky research (Why is the sky blue?).

    Now that’s a very broad category, so you break things down into something more manageable. Like the lifecycle of a specific insect, or the behavior of crowds in shopping centers during holidays.

    The point being that you can absolutely tell someone what to research.

    Now, you are correct in that you cannot dictate the results of research.

    Except that you can, and it’s the second type of research.

    Goal oriented research, or maybe practical research? starts with a goal or a problem. Like a disease. The goal is a cure or prevention. How you get to that point doesn’t matter as long as you do, but in practice the way to meeting that goal is going to be more research centered around understanding the goal or problem.

    Now, all that said, pure Blue Sky research has a guaranteed return on investment. NASA estimates that their return is 3-1. 3 dollars back for every dollar of their budget.

    All that said, there is no ethical reason to constrain research topics or even to reduce spending on science.









  • Eh, it’s honestly safer than you’d think. The size of the reactor plays a huge role in safety.

    A reactor sized for a container ship would be literally incapable of melting down, because there just isn’t enough fuel to get to those temperatures. You could then limit the ship’s speed, and over build the reactor a bit, so that the reactor is never truly stressed during normal operation.

    Then for refueling, you just remove the entire reactor and replace it with a new, fully fueled one every 10 years or so.

    That’s where you want your controls.

    Other than that, yeah it would be safer than oil. A crash just means your reactor casing gets wet.

    The main worry is someone cutting into the reactor to take out the spicy rocks… and there are easier ways to get spicy rocks.

    Columbus was a slave trader up and down the African coastline before he was sponsored to make his voyage in 1492.

    He then enslaved the natives. It was his first response to meeting them. That included child sex slaves. This is an account from Columbus himself talking about how 9 and 10 year old girls were “in high demand”

    He forced most of the people he captured to collect gold for him, or die, and then, because he didn’t actually have the means to feed the people he enslaved, he forced them to live on grass. Most of them starved to death.

    There are accounts of slavers beheading their exhausted slaves rather than go through the effort of releasing them from the chain around their neck.

    No, Columbus was a fucking monster, but Italian Americans of the late 1800s to Early 20th century wanted a “hero” so that the racist assholes would stop being racist toward them. So they appropriated Columbus as an Italian and whitewashed his crimes against humanity.


  • The mycelium is the main body of the fungus, yes, and it’s the entirety of the circle. The mushrooms on the edges are indeed the fruit.

    And it’s every type of mushroom that does this… sort of. Any mushroom that grows along the ground at least. There are plenty of varieties that grow on trees and throughout a leaf pile or such.
