  • The plastic (including polyester fabrics) in your car was most likely derived from petroleum. The car parts were most likely shipped around during manufacturing using combustion engine vehicles. The energy to cast those car parts, probably some of it comes from non renewables. The labour to build the car almost surely comes from other people who consume gas (for example to drive to the EV factory)

    That “100%” renewable energy? The installation and maintenance of it was/is almost certainly done with large industrial equipment and vehicles burning fossil fuels. (Similar issue with production of parts).

    Look, I’m not saying you aren’t making positive choices by choosing renewable options. What I am saying is, while they are more renewable, they aren’t truly 100% renewable when you factor everything involved in it. Fossil fuels are so pervasive in society, it’s virtually impossible to both function in a modern society and not contribute to the consumption of fossil fuels.


  • I think the design philosophy is that each tile represents no more than a single entity at a time, and compact enough that you can arrange the entities in a section to represent a device, room or group.

    In your example, perhaps the room also has a humidifier and/or heater. So in reality, the room temperature entity isn’t truly tightly coupled with the fan. The heater and or humidifier are also a part of the whole.

    With tiles, you are in complete control to arrange groups of entities that represent a larger whole, in whatever scope you like.




  • OP didn’t specifically say “only use the parts that came out of the box”. It’s still ambiguous. Are official mods, like PRUSA MMU modifying? How about after market parts?

    Let me propose a modification tier list:

    • M1 replace a part with a functionally identical one, e.g. replace worn nozzle.
    • M2 upgrade using an official kit provided by the manufacturer to a new, fully versioned design, e.g. Mk3 to Mk3S
    • M3 replace or add a part with an after market part to achieve improved or different performance, e.g. replace brass nozzle with hardened steel nozzle sold by third party
    • M4 replace a part designed by the community
    • M5 design and replace a part yourself for your own custom needs.

    I’ve personally done all 5. I can’t imagine everyone has done all tiers of modifications.

    I’m using off-the shelf CT-clamps with an ESP. Obviously it’s a fair amount more work, but it’s cheaper than a commercial solution, fully offline and no subscriptions, you know exactly what you are getting, and you can build a solution that is just the right size for your application, and infinitely modifiable if your needs change.



  • I have a different take.

    AI today is basically a mechanical school. AI students are trained to give a specific answer. This is at the heart of how all machine learning works, including generative AI. Even image generators do this.

    “Here’s a million examples of what the pixelated representation of a hand looks like; now go and make a derivative copy.”

    This is fine for objective facts, like physics and history. It is useless for art.

    Merely drawing a hand is not art, it’s an objective truth (do typical humans have 5 or 6 fingers?). But art school is not about objective truths. Art school teaches creativity. Specifically challenging ideas and expression.

    AIs can’t fundamentally challenge ideas and express themselves because they lack personal experience, personality and individuality.

    Society at large has been fooled into thinking that speech (LLM) and other generative AI lead to AGI. But the reality is that these models have more in common with encyclopedias and stock image libraries than intelligence.
