joe armstrong gave a talk where he recommends '4 ancient technologies worth learning', or some such. one of them is bash, and another is shell (and emacs, and something else). given that it's joe - i think he knows what he's saying - but it makes no sense with respect to any of these explanations

bash is a shell, it's even in the name: 'Bourne Again Shell'.

But bash is also a programming language. I couldn't find the talk that you're referring to, but Joe might have been referring to

1. 'using the shell' - as in, interacting with your OS through text, learning POSIX commands (which you could be executing with bash) and the mindset you need for shell usage

2. 'using bash' - as in, using bash as a scripting language

also vim > emacs ;)

found it.. it's just a slide in "Joe Armstrong - Keynote: The Forgotten Ideas in Computer Science - Code BEAM SF 2018"

What's the difference between 1. and 2. besides interactivity / REPL? "Using the shell" means inputting the shell language into the interpreter; "using the shell as a scripting language" includes POSIX commands, and the mindset needed is the same in both use cases, no? The beauty of shell is in that exact crossover.
