VS Code makes me feel ... old.

When you move through source code that is managed with git, there is a spot on the bottom of the screen that indicates who last modified that line, and when.

I'm hitting lines that were modified decades ago -- 23, 25, years or more.  Stuff that hasn't been touched since LoanShark wrote it in 1998, stuff that hasn't been touched since IO ERROR (RIP) wrote it in 1999 ... and even that doesn't cover the first ten years during which we didn't use version control.

There's "git log" ... and then there's "git blame" ... and then there's this.  A constant on-screen reminder.  Wow.
