Depending on the job role one is looking for, I would say that it is pretty based. It`s just like comparing programming languages. 70-80% of people that I have met have told me that Python is the most common language used in aerospace industry, however for some, C++ comes under the "old is gold" category. But yes, Python does open a lot of job opportnities than others. I do not think that it is time for Ansys Fluent to go. There is still so much we can use it for, for example, simulating aeroelasticity effect on a wing and being able to test under different conditions. I would say we should be familiar with the basic concepts that these commercial software work with, i.e, CFD and once we start working on a project that require a certain feature, we can choose accordingly.
