A large portion of the housing in San Francisco dates to that era. However, rather than learn from the mistakes made pre-1906, San Francisco just rebuilt things exactly the way they were before. Look how much damage the 1989 earthquake caused, and that was a sub 7.0 earthquake. Another major earthquake would result in similar devastation to the 1906 earthquake.
The best part is the NIMBYs who refuse to allow earthquake deathtraps to be destroyed for more modern buildings. They've become so complacent and ignorant to the reality of a major earthquake, that they feel the character of the city is more important than the lives of the people in it.

It'd sure be nice to be able to clear a few blocks at a time and start over with fresh buildings, but it's more a matter of changing wheels on a bus while it's full of people driving down the street.
