Fortran is better than Julia and interoperable with Julia and any language. Any language as of today is better than Julia. Currently, Julia is a collection of nerd lies and false promises. Look at the recent Julia Discourse post "What is the status of AutoDiff in Julia"? Then read how gloriously the top response describes the situation. Read a few lines more, and you realize there is yet to be a single AutoDiff tool that works effectively and flawlessly in Julia. "Deny the weakness until we fix it" is a typical speaking pattern among JuliaComputing leaders. There is a good reason for it. JuliaComputing is a for-profit company. They have to find a way to return the stakeholders' million-dollar investments. The easiest way for them is to take a Machiavellian approach rather than being realistic, honest, and fair. I know the nerd culture very well. I am familiar with their denial of their weaknesses and flaws, and their nightmares of being the runner-up. I work with them daily. And JuliaComputing staff is a nerd community from head to tail. For a longer list of Julia's flaws that JuliaComputing pushes under the rug, see https://yuri.is/not-julia/ Regarding fairness and honesty, JuliaComputing staff are responsible for >99% of web posts (including HackerNews) that speak highly of Julia and bash any other language, particularly C++, Fortran, MATLAB, Python, R, Rust.
