I agree. It would be better if people understood the costs and benefits of virtual environments and used costs and benefits to guide decisions about how and when to use them.

The general observation I would add is that these change with the level of experience of the person writing the code. I found it helpful and harmless to avoid them when I was experimenting. Now, I use them automatically.

I know that it made people angry, but I think it was reasonable to say that if someone does not know how to edit a file and is not comfortable using the terminal, they are not ready for virtual environments.

Re separation, another option is the one I recommend in the "Environment as Code" post: Right now, I'd suggest installing

- Python3.12

- Python3.11

- Python3.10

Then use edits to `.zprofile` to specify which will be used in any terminal session. It does require the use of an editor to make changes to `.zprofile`, which is where the official versions put the lines that add things to the user PATH. I think it is very helpful to get people familiar with how profiles set PATH for any terminal session and how easy it is to control by commenting out or commenting back in lines in `.zprofile`.

Later, one can introduce them to `.zshrc`.
