Linux

With tools it is often the thing with "newer, easier" and "old reliable" versions. If you want to write and print a text, Word might be easier, but TeX is still more predictable and reliable. And with software like the literally CORE utils, I actually prefer predictable and reliable over fancy eye candy. I could easily see to have them both installed, so everything that worked before still works without the risk of breaking at some odd point, but might use the Rust version like "Rcp -g" if applicable.
