I suppose you think the little kids on airline flights that get to go up to see the cockpit and get little plastic wings are pilots too.
Going up on Bezos' giant thruster willy doesn't make someone an astronaut, it makes them extremely rich and privileged idiots who paid money to experience weightlessness for a few seconds. And to call them astronauts sullies the actual men and women who put their lives on the line for the sake of exploration, humanity, and science.
If I had to be serious, I would say.. the ones who are, or should be, considered astronauts, are the ones who are responsible for "doing things" especially if something doesn't go to plan. Everyone else is just a passenger.
Much like a driver of a regular car or even the one behind the wheel of a semi-autonomous one, they are the driver responsible for their passengers.
A pilot, may well have the plane do everything.. but if those things are not doing what they should be, the pilot should be able to take over and take matters into their own hand, again, responsible for the passengers.
That kind of thing, in a lazy way.. so eh eh calm down mates...
the thing with space as it currently exists, people tend to not have multiple options to be tested as such ... a couple tosses up is all you might get in a life time and if nothing bad happens, how can you differentiate them as an astronaut vs their passengers? they did the same things. (assuming someone who could handle an emergency was included).
so your definition of astronaut has to do more with knowledge while existing in a given place rather than the actions taken in that space.
So there would need to be a test of some sort prior to going up that would designate you as being an astronaut.
But that still requires a new term ...as we would have to call space passengers something until it becomes so commonplace that there doesn't need to be one. Until that term comes around, i think we'll be stuck with astronaut describing both.
