It depends on your definition of "C's philosophy", no sarcasm, and no implied preference by me for any particular definition, as I believe many have merit. Language philosophies evolve, and C, being so many decades old, has evolved a lot. The original philosophy is probably little more than a seed crystal at this point for the several philosophies that have been loaded on to it over the years.

It is probably reasonable to say that Zig is closer to C's current philosophy in practice, which encompasses many additional developments over the decades to deal with various aspects of C and programming real machines that have arisen as both have changes, and Go closer to C's original philosophy of simplicity and relative ease of use. (In modern times, C is not one of the easier languages to use any more, due to significant advancements in the field of making easy-to-use languages. But it was originally intended to be an advancement there itself.)

By similar logic, I can say with a straight face that all of Go, C++, Zig, Rust, and Swift (and more) are "evolutions in general-purpose programming languages like C", despite their wild differences, because the world has gotten larger, and there is room for a lot of variations like that, each addressing different aspects of the newer, larger world.
