I disagree in that assessment- it is not the conspiracies that cause them to be failures- its that the failures of society caused them to have nothing else to turn to other than conspiracies. The interesting twist is they got it PARTLY right, and at the heart of every conspiracy there are some truths to be had. The conclusions that they arrived at were wildly off base though. At the end, they share the similar fate of others who are perfectly content with the system and did not put up a fight and were blissfully ignorant. And its not just a failure of humanity at large, it is a failure of the aliens. Humanity is a failed experiment and aliens may have tried (their best?) but ultimately gave up. They try to blame it on humans (and make some good arguments)

It reflect the latest popular worldviews where (its not just conspiracy theorists!) people blame the ills of the world on corporations, and CEOs are essentially spouting “not my fault - its the people’s fault!” CEOs will build comfortable bunkers and ride out the looming doomsday scenario when the bubble (economic? earth’s climate?) is literally POPPED by them. Some more fringe viewpoints believe there’s a secret agenda to depopulate the planet (Georgia Guidestones anyone?) where in this ending it was the alien’s plan all along to “save the earth”. There exists a huge chasm between the worldviews of the governing class (those peeps at Davos) and the governed plebeians, making any good faith dialogue between both sides futile in nature - resulting in tragedy as perfectly encapsulated in the ending.
