Functional Programing is hard to learn because it literally changes the neural pathways in your brain. Once you learn it, there is no going back : your grey matter will be changed forever. I used it a lot in the past, and less nowadays (Rust), but I occasionally have to teach my coworkers on basic FP principles so they can use and write good Python code. Simple descriptions make the learning more palatable and doesn’t scare people (“you could use a Monoid here” -> “Try using a class like this, with an `empty` and `combine` function, here”). It usually takes about 6 months of daily practice to learn basic FP skills and 1-2 years to go from beginner to “intermediate” level. Occasionally, you might encounter a FP grandmaster who will melt your brain in less than 2 minutes of conversation, some things never change.
