If I’m wrong, I’ll eat my words in a decade and gladly hop in a Terrafugia for a trip to the beach, where I assume cabana-bots will tend to my every need.

You’re talking about changing aircraft classification codes to allow non-licensed operators to ride in a small, heavy plane. You’re talking about producing these on a relatively massive scale and getting the costs down to a point that some one percenters can afford one.
