This is very possible on Arch Linux, moreso than other distributions. After installing Arch, just run the following two commands:
sudo pacman -S xonsh
chsh --shell /usr/bin/xonsh
Bam! You're booting straight into a full Python environment when you turn on your computer. This is similarly achievable with other languages as well, including BASIC.How about Processing. https://processing.org/

Arch Linux does not help with this, unless you make it boot into a VIC-20 emulator or something. Arch can help with boot speed, but once you're booted you're back in a full modern OS. So fine, install VSCode and Python... okay, now you get to figure out libraries. Manage terminals. Arrange a filesystem. This is not getting you closer to the VIC-20 or C64's "boot into BASIC".
