  • I’m saying you should do your own research

    This is the calling card slogan of someone who’s bought into reality rejection…

    The educated world is built on a web of trust whereupon subject matter experts must necessarily yield to others when something is outside of their realm of expertise. I am a planetary scientist and geophysicist and spent nearly a decade studying. I am constantly learning things in my own field, and by no means do I have a full grasp on every detail. But I can call out BS when someone talks about orbital mechanics or earthquakes or whatever. I do not, however, know anything about the digestive tract of my cat and yield to the veterinarian who has spent their whole life becoming an expert on these sorts of things. I don’t argue with the vet that I’ve done my own research (watched a few youtube videos) and thus am qualified to disagree with them. Because objectively I know less than them on that subject and no cursory review will solve my ignorance.

    When rating the bias of news organizations, what qualifications do you have so that you can do your own research? Do you have fundamental knowledge of the journalistic process? Is the media source covering a topic you are a subject matter expert in? Or are you just lashing out because it doesn’t vibe with your worldview?



  • So, federated network advantages here: you can always modify your instance’s hosting code to patch this out, at least for the users on your instance.

    What you cannot do is prevent other federated instances from publishing the votes submitted to content on their instance. But if you’re accessing that content through your local instance, they can modify the upvote button to pop up a dialog saying something like: “The instance that hosts this content has elected to make usernames visible for upvote/downvote. Would you still like to vote?”

    Personally: In many ways I don’t mind. I’m on the internet with my real name. I don’t mind being accountable for my behaviour online. I might be a little more cautious about upvoting something controversial or NSFW, but largely it wouldn’t change my behaviour.




  • I admire your optimism and I hope you’re correct. At least with the little “city commuters” it probably even makes sense. But lithium battery tech also continues to improve – so catching up with 2021 is great, but the goalposts keep moving.

    There will be an absolute limit coming from physics and chemistry, and lithium is a smaller, lighter ion. In the theoretical limits, it will absolutely be the winner.

    But from a practical perspective, if Na-ion becomes light enough and (more importantly) cheap enough, it will probably win the economic game in the longer term.

    Plus we can make Na-ion batteries in-situ elsewhere in the solar system without having to first finding concentrations of lithium – so high tech space industry stuff will likely more towards Na-ion, which will fund some development.







  • I’m actually surprised it has taken this long.

    What surprises me even more is that organized crime hasn’t gotten on board much (yet). Like, screw drive by shootings – drone dropped grenades on rival gangs and such.

    Or that drones haven’t been used for “school shooting” type mass casualty attacks.

    Or that foreign countries haven’t snuck in with a sea can full of drones which fan out and attack infrastructure.

    Imagine a cruise missile as a drone carrier that just scatters anti-personnel drones along a flight path, each just finding a person indiscriminately.

    If there’s anything that Ukraine is teaching us, it’s that we don’t have countermeasures (yet). The autonomous versions are even scarier.
