To be clear, that developer survey asked:

    > Which programming, scripting, and markup languages have you done extensive development work in over the past year, and which do you want to work in over the next year?

Also, in the same results, just above Rust, I see:

    > PowerShell 13.8%

Powershell is probably more popular, it's used a lot for IT stuff so we never hear about it but it's there.
