The problem with trivial ops like stack manipulations is that they don't really do anything useful, but they can take as long as multiply in the pipeline.
Stack machines made more sense when memory was limited (small opcodes) and there were no hardware multiplies, but these days they make no sense.
I don't understand all the vague nostalgia for something that never could have panned out outside of the creaky old Apollo flight computer or something.
Fair point. That said it's not nostalgia, Baker's article was about linear logic and that forth was naturally fit for this. Cue Rust borrowing and you see why it may be of interest (if baker was right of course).
