C is the most perfect language, so simple yet so powerful. That’s why I like C and Arch Linux, made by and for programmers, with no stupidity tolerated. I wish I could use Arch on mobile. That would be epic.
You totally can. I've got a Termux with NixOS installed on my Android handset. There's also Phosh if you want a fully Arch-native install on your phone.
Wouldn't be my choice for a mobile OS, but I don't see any roadblocks to using it.
