I'm not tired, I'm afraid.
First, I'm afraid of technological unemployment.
In the past, automation meant that workers could move into non-automated jobs, if they were skilled enough. But superhuman AI seems now only few years away. It will be our last invention, it will mean total automation. There will be hardly any, if any, jobs left only a human can do.
Many countries will likely move away from a job-based market economy. But technological progress will not stop. The US, owning all the major AI labs, will leave all other societies behind. Except China perhaps. Everyone else in the world will be poor by comparison, even if they will have access to technology we can only dream of today.
Second, I'm afraid of war. An AI arms race between the US and China seems already inevitable. A hot war with superintelligent AI weapons could be disastrous for the whole biosphere.
Finally, I'm afraid that we may forever lose control to superintelligence.
In nature we rarely see less intelligent species controlling more intelligent ones. It is unclear whether we can sufficiently align superintelligence to have only humanity's best interests in mind, like a parent cares for their children. Superintelligent AI might conclude that humans are no more important in the grand scheme of things than bugs are to us.
And if AI will let us live, but continue to pursue its own goals, humanity will from then on only be a small footnote in the history of intelligence. That relatively unintelligent species from the planet "Earth" that gave rise to advanced intelligence in the cosmos.
