no, null pointers are enforced safe at the type level in zig, as are array bounds, this eliminates huge classes of errors, so you are not "responsible for everything". unlike c, you often (unless highly tuned performance is needed) do not have to resort to opaque void pointers, and the compiler gives you typesafety on that, another major footgun in c.

also operators and integer types are unambiguous, and there is no UB in safe compilation modes.

It's arguably much better than C, not "slightly better than C"
