I'd mean people who don't know linux in particular but are marginally tech-savy.
Mint has been described as "the distro your granny can use" (and some do), but it does require some knowledge to at least install it — but it's nothing a tutorial somewhere won't help with, it's a low bar.
Maybe.
Still, there are other sources of bugs beyond memory management.
And i'd rather have GPL-ed potentially unsafe C code to... closed-source Rust code.
