I wouldn't sail this ship if I were you
1. When you fully automate your award-winning lawn flamingo production line, right down to the roving robots scavenging organic material for plastics production to reduce costs and environmental impact, only it turns out nobody thought to inform the robots that people are not a valid source of organic material and everybody ends up being recycled into lawn flamingos.
2. When scientists ingeniously engineer a virus capable of wiping out humanity, resulting in a highly-cited paper and, after a series of hilarious vial mix-ups, cross-contamination episodes and doors propped open by cleaners, the wiping out of humanity.
3. When it turns out Venus is in fact a far-future planet Earth which was sent back through time and space by the final few remaining humans as a last-ditch attempt to convince the twenty-first century to stop with the global warming stuff already, but nobody figures out the distinctive temporal and mass-related signatures of planetary time travel until significantly too late.
4. When humanity decides to distract itself with a giant outbreak of memes mocking bears, and the bears decide they’ve had enough and beam up en masse to Pluto to establish an undersea-forest city in the planet’s core. It turns out that bear shit was a vital part of the planet’s ecosystem and, with no bears shitting in the woods, the woods stop working and nobody has any oxygen any more.
5. When a normal volcano gets upgraded to a megavolcano as part of a marketing exercise, decides it enjoys the attention, and puts in the work and planning needed to become a gigavolcano. Humanity sure is impressed.
6. When enthusiastic but short-sighted aliens bent on making first contact before anyone else accidentally reverse their moon-sized spaceship into Sweden.
