Die Level Progress(DPU): So much human progress that if a person from the past is sent through a time machine to witness it, would literary die.
- In order for someone to be transported into the future and die from the level of shock they’d experience, they have to go enough years ahead that a “die level of progress” or a Die Progress Unit (DPU) has been achieved
- A DPU took over 100,000 years in hunter-gatherer times, but at the post-Agricultural Revolution rate, it only took about 12,000 Years
- The post-Industrial Revolution world has moved so quickly that a 1750 person only needs to go forward a couple hundred years for a DPU to happen
