Is there a 'right amount' of AI? direct repository linkDebated

Participants debate whether AI-generated code constitutes meaningful creativity or merely derivative plagiarism, with some arguing it crowds out human artistry while others view it as a natural evolution of tool-assisted development. The discussion also highlights a sharp divide between those who see AI ethics as comparable to other industrial harms and those who emphasize its unique capacity to disrupt creative labor.

Every time I sit down to do anything non-trivial in OpenSCAD, I wonder if there isn't some better way of representing things --- I'd like for there to to be something better, but usually the solution to any problem put forth on the OpenSCAD mailing list is: "learn this bit of math and apply it thusly". That said, I gave up on all this and have switched over to just modeling toolpaths: https://github.com/WillAdams/gcodepreview that way, I'm certain that whatever is modeled can actually be made, and I'm also certain that the modeling is not limited by arbitrary things. I've got an idea for a woodworking joint which I haven't been able to model so as to cut out in any other program, and I'm hoping this will let me finally manage it. I've been using OpenSCAD Graph Editor (OSGE) as a front-end: https://github.com/derkork/openscad-graph-editor
