I run it, it’s kinda cool
Bonkers that anyone would start a social media app in C in 2025. "No JavaScript" but you're just one buffer overflow from arbitrary code execution.
C is also faster than JavaScript, uses less memory, and memory safety isn't impossible in C either. I wouldn't consider a scripting language to even be a choice for writing a backend server if I can use a compiled language instead.

In practice it is.

Neat.
How is that?
C is a "memory unsafe" language. There are whole categories of security vulnerabilities that simply aren't possible in memory-safe languages that C allows. There is no good reason to continue using C anymore for new projects if you care at all about security.

I’m a rust fan, but may I remind you that the Linux kernel is mostly C?
No. Go away. That's not "starting a social media app" now is it?
Besides, even the Linux team has started the shift away from C.
Edit: besides - "Linux does it" doesn't mean it's beyond criticism. Linux has had numerous security vulnerabilities due to C.
Please write the "C considered harmful blog post". I just want to see everyone's faces. Pleeeeeease.
Others have written on the topic. Including Greg KH - one of the major Linux maintainers.
Yes but those are inferior because they aren't in a rage-baiting meme format
