Mine is for consolidation of knowledge. For instance, when I study math and I write a pen and paper proof as an exercise I then write a clean note from scratch and link to other theorems or corollary notes I have etc. Similar stuff for computer science or programming. I find out that this process solidifies the work I'd already done and make it less likely to forget.

I also think people get a bit too dogmatic about the ways to use technology to help improve your life. Like, what the heck complex rules about Zettelkasten? I don't know what kind of expectations they have going into this. Do these "influencers" telling you how to use it sell the promise of the ultra-intelligent god from the popular meme? Just open the damn editor and write, you will find what works for you through tinkering and iteration.

As for DOGE, I live in a different country and not really care to be frank, as an external observer the US is a testbed. We will see what kinds of results going all guns blazing to reduce fraud in government, instead of asking nicely, will produce in due time. As your leftist friend said, you need to break some eggs to make an omelette.

That's a bit ironic given leftist claims that men can become women and vice-versa.

Generally, they never made any real decisions or have any real vision to inspire with and execute.
