Hence the "or better" part of my comment. :-)

I would be happy if we saw more things being written in something like
Ada or a Wirth style language.

My wish doesn't change the fact that C is still a better language
than assembly language.

And yes, I've written code in lots of assembly languages (I like
the ARM ISA for example), C and C++, Ada/Wirth style languages, and
a good range of other languages. My opinions are based on actual
experience.

Simon.
