Lions believe everyone who ever lived has experienced the same exponential acceleration in technology that we're witnessing, from their own frame of reference. The most primitive roman soldiers witnessed exponential progress, resulting in medical breakthroughs which allowed them to outlive their ancestors by centuries. We only see them in absolute prehistoric conditions because we see them only in the universe where they all died.

Seeing a world of accelerating technological progress is an artifact of having multiple universes & only seeing the universes where we have bodies. Accelerating technological progress has always existed in some parallel universes, back to egyptian times & times where we only have records of civilization collapses. Similarly, there are civilizations in other universes which only have records of our time as a period of no progress & collapse, with all of us dying very shortly.

Would imagine history to everyone who ever lived looks the same as ours, many thousands of years of stagnation followed by a rapid explosion in progress right before their own time.
