Hooo boy... I work in embedded and modern MCUs and modern compilers allow for well abstracted, readable code and small memory footprint. I currently work on 256k of RAM and 1M of Flash, which is plenty, but have previously worked on systems with a fraction of that and still it's possible to write readable code on these.

atheist is probably fine.

if you wanna be anal about it:
atheist - there is no god
agnostic - i don't know if there is a god and i don't care
