It remains weird and disturbing to me that "AWS" is treated as a skill. Not "cloud system management", but " AWS ". Edit: I do understand why it can be lucrative to have expertise with a specific cloud provider. It's just the status quo of these services being their own unique silos that disturbs me: I would personally be wary of making "ability to effectively use Amazon's servers" a pillar of my career.
With the exception of OpenFOAM, all of these software are proprietary, largely non-interoperable, and expensive—like thousands to tens of thousands of dollars for the cheapest option with basic functionality kind of expensive; like I can never imagine opening my independent consultancy business because how expensive the basic tools are kind of expensive.
Outside of programming, this is the norm. The number of free and/or open-source tools available to a mechanical engineer or an electrical engineer are infinitesimally small and it is almost impossible to do a serious engineering project with only free tools.
Since this is quite lucrative for the companies making those tools, I can only imagine tech companies would be more than happy to lead us to a future where software engineering is similar in this regard to other engineering disciplines. Perhaps this is what happens when a field matures, and since software is maturing, it will become more and more like this as the time goes on.
