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?
