so no way or time to switch between that amount of pistons, turboprops, GA jets, airliner jets etc etc.
20,000 hours for a professional aviator can be had without even trying hard aerobat. The highest time gal, Evelyn Johnson, gave it up after 57,635.4 hours, Max Conrad had 52,929, and the record holder, Ed Long passed away with in excess of 65,000.
i personally know very few +20000 hours pilots, none of them would spend hours for hours in a public anonymous forum
I can confirm there are posters here with 20,000, and not all of them are anonymous. They just don't have a life.
