My thoughts exactly. In Europe it's part of our social welfare

Well, you're already on a Debian based distro and not Ubuntu. Let it do it's thing in the most boring way :D

This is the future we were promised, dumb machines doing work 24/7. I'd change it to Debian but you stick with whatever works best for you.

I also pay for it and watch it on my android TV. And I completely agree with you. But for now it's my main source of TV and I mainly follow channels I subscribe. I don't listen to music on YT, i do follow some live music channels

Thank you for the write up. It's very helpful.
I'd pick another CPU (even Intel) but I understand that you're bound to the motherboard. I'm looking for a SFF build, what's your PC-case?

Security starts first with you. Most of the attacks are done though social engineering. Email phishing, dodgy webpage logins. Normal password security behaviour should fine for you to use the pc. More importantly, what is the distro you're using? Maybe consider using Flatpaks for the apps, they tend to offer more restrictions on access to the system. (Installing the torrent app as a Flatpak and only give it permissions to a specific folder) One of things I tend to do is install chromium just to login on my Google apps, Gmail, YT. But I'm more of a non data sharing freak.

Nice work. Why move from plasma to hyprland? Install both and login on the environment you want at any time. I have qtile, plasma and hyprland

Have a look at this.
