"FORTRAN: Unlikely to influence anything in the future due to remarkably poor design" I guess the author of this sentence likely does not know anything about Fortran. They do not even know that the language has NOT been called FORTRAN for more than 3 decades. They do not even know about the latest release of Fortran in 2018. They are at best showcasing your ignorance and bias, by not providing any arguments as to why people should take their comments and advice seriously.

That made me chuckle, I still work on Fortran applications. Some were written in the 70s/80s, but maybe that just means the industries I've worked in are a bit _inflexible_?

What lessons would you say are left to be drawn from Fortran?

Those lessons that C++20 is still learning from Fortran
