You may have been called dumb before. You may have thought that other people are dumb. But if we ever obtain superintelligent Artificial Intelligence (AI), the difference in IQ between Einstein and the dumbest human will be insignificant compared to the difference between Einstein and the AI.
Since a human-level AI would be able to improve itself at an exponentially faster rate, the difference between Einstein and the AI could become as drastic as the difference between Einstein and an ant in a few short years.
Use this shirt to get back at everyone who called you dumb by reminding them that they will also be as dumb as a human compared to our future AI overlords.
