So the fourth ship has cpt, crew, dest and course set - but ... what if instruments determining the course are broken? (that aims towards a distortion of perception - maybe due to schizophrenia). Take that previous ship assuming the instruments are sufficiently fine - so it will reach a destination - great - but how was that destination chosen to begin with? Was it maybe just the result of what parents, peers, society expected or led you to believe to be the right destination? Like working a lot to finally retire in a house next to a lake (just making something generic up here) - the cpt will see the destination long before they reach it and before that she'll have had plenty of time to overthink the endeavour - and it dawns on him she's on his way to somewhere she actually doesn't want to go - what now? She's too old to change course somewhere else - at least that's what she thinks - and anyway where would he go now? What if the map is basically bullshit? What if the destination is destroyed by a typhoon (<> illness) during course? What if the appeal of the destination is its uniqueness but b/c TV tells every cpt to go there it looses it and becomes overcrowded by disrespectful and obnoxious people?

Maybe the cpt was actually - in hindsight - coming from a pretty decent place. She was just too impatient and immature to realize it. Then she watches a biopic about Jeff Bezos and his "regret minimization framework" (aka FOMO) - so she thought she has to take that risk just because she might regret it. should have never set sail anywhere. in another alternative universe she does everything above (the wrong thing technically) but his home town got nuked and she thinks - good that I left. better live in a boring house next to some boring lake with a husband that I don't love anymore than being dead or crippled by cancer due to the radiation.
