CAD is an exception, yes. Also a lot of stuff related to commercial aviation, because of the regulations. I was talking about comp sci, statistics, big data etc.

that software has (or had) Unix roots from ages ago and the clunky nature of anything related to Unix comes through.

It's the other way around. It is extremely easy to make simple UNIX scripts. And it is extremely easy to string together a bunch of such simple scripts to make larger software. Windows does not follow the UNIX philosophy, making it difficult for different programmes to talk to each other.

Someone's been feeding you bullshit.

I'm talking from personal experience. I write R, python and bash scripts to take data from machines, analyse it and draw graphs and charts based on it. I use three languages and multiple machines. But thanks to the UNIX emphasis on modularity, I can connect all of this into one automated pipeline. And if tomorrow one machine is replaced, I will only have to change a few lines of the script, again thanks to modularity.

Don't get me wrong, Windows has its advantages - better gaming support, 'safety rails' that prevent you nuking your system, better drivers for peripherals, and so on. But software installation is not one of them.
