Go can be understood as an improved C that keeps much of C's simplicity but adds small, powerful features like interfaces and channels and garbage collection

Go fixes C's well-understood flaws (declaration resembling use, unintuitive operator precedence, unrestricted address math, silent casting, zero-terminated strings, etc.)

Go puts essential C idioms directly into the language (pointer/length is formalized as slices, packages are part of the language instead of just being naming convention, etc.)

Go is mature, stable, widely-used, well-supported, and well-understood. C++ is a clumsy mess, but C is quite elegant and Go is a continuation/modernization/enhancement of that

If you like C, you will love Go

Good stuff. There is another >5 minute tutorial here:

This website has something similar for nearly every language:

I think this is pretty good but I think you ought to commit a paragraph to pointers as well.

I like C but strongly dislike Go. They share nothing other than having a small(ish) feature set.

I'm not a C fan but isn't Zig much closer to C's philosophy while fixing bad parts than Go? Especially due to the garbage collection, at which point Go suddenly competes with many more simple languages.
