I recently learned that when they talk about a life expectancy of eg. 80 years, it's assuming that the future looks similar to the past. But with exponential progress in technology, that doesn't seem like a good assumption. For example, according to Bostrom's survey (90% likelihood), the median pessimistic year for AGI is 2075.
So then, taking into account technological progress, what do we expect life expectancy to be?
The life expectancy is infinite, but the median is finite unless the probability of immortality is at least 50%.
