The one about Bitcoin being invented by an AI, which is now accumulating a huge amount of computer power by greedy humans building big bitcoin mining centres to make money, but all they are doing is building an ultra resilient network for the AI to run on. The AI also has a huge amount of wealth to now pay anonymously to humans to do it's dirty work in the physical world.
A superintelligence at some point wants more computation and robot arms - given robot arms aren't all that great, money is the next best thing, as humans will do anything for bigger numbers on their bank account.
For me, it's truely terrifying.

When light bulbs were created, they lasted forever. Producers noticed that would be a limited business and engineered them to go out after a certain period so they could continuously sell them.

Human are nothing more than a virus destroying the larger organism earth. Earth will eventually get a fever in an attempt to rid herself of us.
