When I first tried to install Arch, I gave up when I got confused with the documentation for an encrypted install.

But since I’ve discovered archinstall, it’s a dream to do and arguably faster to install than other distros.

What you are talking about is the operating system, not the cpu.

The ARM architecture allows much more performance for less power when compared to AMD64, because it runs simpler instructions.

The change to ARM chips on laptops will not make them work like phones, with the exception of much better standby.

Unfortunately, that doesn't work in Beehaw.
