It appears you've been infected with what I like to call "the Dijkstra
syndrome" [*], quoting

"The tools we use have a profound (and devious!) influence on our
thinking habits, and, therefore, on our thinking abilities."

spoiling us. I can't seem able to think like spreadsheets anymore
either, because of R.
