A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

'3d-printing a screw' is a way to describe how AI integration is stupid most of the time (lemmy.dbzer0.com)

Listening to another pitch about how AI can empower workers at various jobs across my industry, I was striken by the comparison in the title

3d printing, just like generative models, have it's actual niche uses, where it's obvious downsides are irrelevant and they come handy, e.g. prototyping, replacements, small-series production

Where it comes to the top-down AI promotion trend, it feels not unlike the idea of printing the whole product - a car, or a house, from the smallest details - applying the least effective method, doomed to have a worse than average outcome due to technological limitations

And screws, the thing that we nailed down long before, and that is completely incompatible with that mode of production, is a screaming, growling, shrieking example of how helpful tech can be mispurposed in the most stupid way

There are a lot of things that FDM printing will likely never be better than say injection moulding, and the main thing is speed, as in quantity over time. A single 3d printer might be able to make a plate full of maybe a dozen widgets in a few hours, and in that time, the injection moulding machine will have tens of thousands produced at a higher quality.

On top, 3d printing would require more staff to troubleshoot, clean, re-start prints, remove scaffolding from finished items, sand/polish to remove the layer lines, etc.

What it's great for in an industrial setting, is prototyping. For example, a case for something can be printed, and the plate can be filled with several variants. If a flaw is found or changes needed, then a new batch can get whipped up on the same printer. Once a design is found that is acceptable, the CAD drawings get sent to have moulds created.
