> I got my start as a script kiddie writing automations for this system with Microsoft Access, VBA, and SendKeys to automate data entry

I've done exactly this for the likes of JP Morgan Chase. Many of their core banking systems are some COBOL/Fortran mainframe (that I know nothing about) but the interface through a TUI client. When they have a desire to work in a more modern fashion, it's SendKeys to the rescue. There's definitely still a lot of TUI's that run the world.
