If you read scorn, you read wrong.

Rust is manifestly a better language than C for any use where it works at all. But it is not the only, and often enough not the wisest choice. Everyone chooses for their own reasons, and wisdom may come too late, but late is better than never.

I wasn't the only who read it that way. Couple of examples:

"Complacency around bugs the Rust compiler permits is encouraged by neglect as part of the Holy Mission to drive Rust into universal enterprise use"

Sounds like a conspiracy with no evidence cited.

"No Holy Mission drives such activity"

Sounds scornful to me. If you didn't intend to be read that way, you should rephrase these.

Sadly today they are precisely one language suitable for writing safe low-level code. Well… one and half, essentially: Rust and “GCC's C with set of flags Linus insisted on being added to GCC”. C++ is flat-out unsuitable.

And as you readily admit Rust is the best of these.

One?

Did everyone suddenly forget about Ada and it’s sinking Spark? These two have been in use in mission critical work for decades.

Ada for the win

Indeed. I think that Ada would be an excellent choice for a safer more reliable set of utilities.

You are the first simultaneous Rust promoter and C apologist I have encountered. You might be all alone in the world.

Why? C is a de-facto systems language (duh), and Rust is the only modern-ish alternative. I believe that C++ can be used as well, but it has way too many drawbacks to justify rewrite of low-level systems in C++.
