Not a programmer, but I wrote my first proper script (lots of if/else) at 37 and the world of automation and scripting/programming opened up to me. I work in mostly a Microsoft land, Office 365 and Azure so I work mostly in PowerShell 5 and 7. My daily driver for work is Pop_OS! 20.04 as PowerShell 7 is decently multiplatform now. Current interests/learning are Python and Nim. I don't think you are ever to old to get started.
