There is no substitute for skill. You probably know this from flying helicopters. That panic button is the equivalent of the auto recover devices they have for helicopters. Will it save the vehicle from an incompetent pilot? Maybe. Will it cause you to get good flights in if you haven't practiced the skills? Not at all. To my mind, FPV is something to get into after you've mastered your trainer and then your second airplane/sport plane. When you can land on a dime, do straight takeoffs, do basic aerobatics and make it look pretty good, and never lose orientation, that's the time to switch to FPV flying. And the smartest way is to do it on a buddy box with another experienced pilot who is comfortable with your plane. At least for the first few flights, that will let you not have to worry about your takeoffs and landings, and then when you're ready you'll have someone to talk you down so you can learn how a good landing looks through the goggles.
