Tools are valid regarding a context (when you have a hammer everything is a nail etc.). In the industrial context, Julia is not valid. In the research/education, it is valid. It does not mean that Julia will never be relevant in research.
Our upcoming JuliaCon 2024 has a significant number of industrial talks and a minisymposium. ASML uses Julia quite widely in a definitively industrial context.
What I mean is as a worker or student, I want to know if the tools I spend time on will be relevant in the industry. And I think I have more chance to meet companies working with MATLAB than Julia.
But if I want to work at asml Julia might be a good fit ofc.
