Not everyone knew C.

Lack of trust: what was it doing behind the scenes? What's if it just went and ..... allocated memory all by itself!!

Optimization wasn't so good back then. People believed that they could write better assembly. For speed and size.

Memory was tight. C would include big libraries even if only one function was needed. If "hello world" was several k in size, that added to the suspicion (even though that was a fixed overhead in practice).

Now we know we can't write better C.

Though my teacher in tech school a few years ago ran an entire OS, where everything is written in assembler. What was it?

Maybe Kolibri OS?

Its an amazing project, booting from a single floppy disk into a full graphical OS with multiple tools. And that on PCs with almost no RAM.

I sometimes use it to backup ancient PCs.

Yeah, sounds like this, thanks!

Makes me wonder why the suckless guys don't hook in there.
