I am a wannabe, and i do worry about recession and oil question.
But people will need to travel, borders are gone (in europe especially) and we're moving globally very much. Companies everywhere in the world seek opportunities to enlarge/expand their business globally (wreight, business travel), people are getting wealthier in not-so-developed countries (i.e. China, India..) and they will have change to see something else than their backyards.
But oil runs out, there will come time when pilots may lose their jobs, but i believe it will recover very fast, because like i said - we need to travel. No matter is the energy we use oil, hydrogen, nuclear,tidal,solar etc. We have engineers which will make it possible, it is a smaller challenge than heavier-than- air flight back then
