Our technology jumped from sticks and stones to interplanetary rockets in 10,000 or so years after sticking to those sticks and stones for about 200,000 - 250,000 years.
We still have had people living in the Stone Age during ww2 and some still do today.
We probably know less about how a civilization might develop into a technological one than we know about how life can evolve.
