Starting a new OS in those languages today would be heavily questionable.

Same applies to C, 10 years younger than them, less capable in language security, in an highly connected world, yet people keep doing it.

You're really pettyfogging simply to be contrarian. C is a language with a large and active community, and is still the most common/popular language in its fields. Algol-68 and Fortran are not. It has nothing to do with age of the language and everything to do with modern-day usefilledness.

The fact that you're unable to distinguish the difference means you're being purposefully obtuse and annoying or are simply naive.

This part is really unnecessary. Parent is most likely not "unable to distinguish" and name calling poisons the air and cheapens your other point which I think is good.

Fair point, I apologize for the petty comments. They were unnecessary. I sometimes have a low bar for intentional contrarianism/obtuseness at the expense of useful discourse.

A usefulness out of historical accidents and sunken cost.

Which has absolutely nothing to do with the original point.

It definitely has everything to do with sensible decisions.

Ok.
