I don't mean to derail the thread into defining "amateur astronomer," so let me rephrase the question: what are we trying to sell to a prospective young astronomer? Just owning a telescope? Seeing something pretty through a telescope? The intellectual stimulation of learning and greater understanding of the universe? A feeling of accomplishment in the skill of exploring space by using a telescope? etc.
I just find a lot of the criticisms of young people being put here to be ironic and funny. They are criticized for being too shallow for amateur astronomy, and then given a very shallow reason to join: you might see something pretty. They are criticized for using their electronic devices too much, and the criticism is being made by someone using an electronic device.
At least the subject matter of astronomy is real...unlike that of video games.
