  • Many people are being forced to use it though — this is where much of the ire is coming from. These people are likely in the minority though. Something that’s much more concerning though is the use of AI that affects us, but we don’t get a say: doctors being made to use generative AI transcription tools (which perform worse than established audio transcription software that doesn’t use AI). The people pushing doctors to use AI are doing it to wring more productivity out of them — more patients in less time. This means that even if a patient doesn’t end up with AI hallucinations in their medical records, their experience seeing their doctor will likely be worse.

    Cases like this are becoming less niche as time progresses, despite mounting research showing the harms of these technologies when they’re applied in this way. Increasingly we are being put into situations where AI tools aren’t something to be used by us (which is something you can often opt out of), but things to be used on us. We don’t find out until something goes wrong, and when it does, regular people can struggle to challenge the situation (the example coming to mind here is false positives in facial recognition systems being used by the police. It is leading to more innocent people being wrongfully arrested)






  • You’re right that I didn’t sufficiently consider the “was” in that sentence. Perhaps there’s something I’m missing though, because I haven’t seen anything that would suggest X is left. When I put my right hand in the position indicated in the OP, my index finger (Y) points upwards, with my thumb (X) pointing right, making an L shape. My middle finger (z) comes out towards me.

    However, most of my experience with coordinate systems is with abstract, mathsy stuff, and I don’t have much experience with any of these softwares; there may be something obvious that I’m missing.


  • I don’t think that’s correct. Here’s a drawing I did when trying to get my head around this.

    drawing

    I find that trying to make sense of terms like “to the left” tricky when we can rotate the directional cube any way we want. For example, in my drawing for “Y-up, left handed”, the red X axis is pointed leftwards. However, we could rotate the unit vector cube so that the X axis is pointed right, and the Y axis is pointing up (i.e. the orientation we’re most familiar with for 2D graphs). The Z axis would then be pointing away from us, into the plane of the paper/screen.

    In contrast, if we oriented the Y-up right-handed cube in the same way, then the Z axis would be oriented as if to come out of the plane of the screen/page, towards us.

    These distinctions only matter when we add a third dimension, so the left or right handedness is basically a question of "when we add the third axis to a 2D square made by the other two axes, does the third axis come towards us or away from us? I apologise if this hasn’t made things any clearer — I am able to make things make sense by imagining the rotations in my head, but not everyone is able to visualise them like that.







  • A few years ago, I read about how Mary Molony was an Irish Suffragette who disrupted a speech Winston Churchill was giving in Dundee by ringing a bell every time he tried to speak. She wanted him to apologise for remarks he had made about the women’s suffrage movement.

    I remember when I read this, it reeked of something awesome that you find online that’s actually false (the story was shared on social media via a captioned photo with no sources), so I went digging for a proper source to check. I found some newspaper articles from 1908 and I learned that this event did happen, but also that people fucking hated Molony for this. There was a lot of “see, this is why everyone hates the Suffragettes”. (Sorry for saying this and then not sourcing)

    It makes sense that people would be salty - Churchill was an asshole, but also a great orator, so I can see why one might be disappointed in missing the chance to see him speak, but I was shocked at the level of vitriol aimed at Molony and other Suffragettes from the time. Until this I hadn’t realised just how unpopular they were at the time. It’s drastically changed my perspective on protests and public perception.
