The issue here is; Python and C# are entirely different tools, for entirely different environments, and an entirely different set of users.

It's kind of like saying, "Why I stopped using hammers and switched to screwdrivers."

If you start coding in C# in (for example) an environment filled with scientists or data scientists, you'll be hated and eventually out of a job.

If you code in Python for, say, Windows desktop software - the same.
