From knives to ammunition and missiles, all these things are made with rocks (minerals) so, in a sense, humans still use rocks to fight each other. As they say: "War... War never changes..."

I'm not sure if it's a São Paulo (as in the state, not the city) thing, but I had English classes when I was in public high school ("ensino médio"). They weren't the best English courses out there (i.e. they weren't comparable to Brazilian schools that specialize in English courses such as CCAA, CNA, Fisk and Wizard), but they offered a good start for those who had no prior knowledge of the English language. It's also worth mentioning that people who work in IT have more potential to come into contact with communication in English because a lot of documentation is in English. But I totally agree with you that most of the population does not have quality access to English courses.

Despite the lack of apps, Windows Phone was very good for me at that time, as I had two Lumias. They were quite cheap but rather powerful (again, despite the lack of apps like internet banking, but they did have Whatsapp and Telegram). I left WP and Lumia when Whatsapp ended its support for WP in December 2019 (if I remember correctly), and Nokia's Android phones were expensive at the time, so I tried the Asus Zenfone (because I see Asus as a good PC hardware manufacturer). Two years later, my Zenfone started to drain faster because the battery started to swell, so I bought a Nokia with Android, which I still use nowadays. This latest acquisition made me realize that, indeed, Nokia is no longer the same: although it has the Nokia's bold design ("almost indestructible"), it is a slow smartphone. I fixed my Zenfone battery and used both phones simultaneously for another two years, when the Zenfone battery stopped holding a charge again (although, this time, it didn't swell). Since I couldn't find a replacement battery for the Zenfone, I stuck with the Nokia, but soon I'll try another brand like Xiaomi, or maybe Asus again since my previous experience with a Zenfone was really good.

Actually, it's training a self-driving humanoid robot that's supposed to climb stairs in order to terminate any potential John Connor that's inside a house upstairs.

Dead Internet Theory all over again.

I'm somewhat pessimistic. Even if humans zeroed every single pollution, it won't be free on us, there's a bill to be paid, and Mother Nature will effectively charge us for this debt. And it'll not be cheap.

blares a loud siren

IIRC, it was a high-pitched sound, like a screeching cicada.

I want it for KDE lol

If you have Plasma Integration (KDE), you can create a task for sending the link directly to Firefox without copying and pasting. Plasma Integration shows as a context menu item inside chrome, if you use KDE.

Back in the days I used to use Windows, I did use Linux as a developer sometimes, yet I was sticking to a daily usage of Windows... Until Windows 10, when Windows started to be aggressive on how it won't let me control my own machine (e.g. I couldn't disable updates the way I wanted, I couldn't run some softwares, I couldn't this and I couldn't that). Then I said "enough" and started using Linux on a daily basis, firstly Ubuntu, then I started to experiment on other Linux distros, until I finally landed on Arch Linux, as it's highly customizable and let me have full control of my own machine, not being stuck to specific DEs (I know that distros like Ubuntu allow the user to uninstall the current DE, or install other simultaneous DEs, but Arch comes without any DE from scratch). I've been using Linux on a daily basis for almost a decade now and I don't miss Windows.

Aside from SearXNG, I didn't know about these search engines until your recommendation. Thanks to Wiby and Marginalia, I found old rich content (old BBS list conversations, for example) that I was looking for, regarding studies on the occult and esotericism. Thank you so much!
