Does life extension (without other technological progress to make the world in general safer) lead to more cautious life styles? The longer the expected years left, the more value there is in just staying alive compared to taking risks. Since death would mean missing out on all the positive experiences for the rest of one's life, I think an expected value calculation would show that even a small risk is not worth taking. Does this mean all risks that don't get magically fixed due to life extension (for example, activities like riding a motorcycle or driving on the highway seem risky even if we have life extension technology) are not worth taking? (There is the obvious exception where if one knows when one is going to die, then one can take more risks just like in a pre-life extension world as one reaches the end of one's life.)
I haven't thought about this much, and wouldn't be surprised if I am making a silly error (in which case, I would appreciate having it pointed out to me!).
Suppose there's a life extension treatment that resets someone to age 20. It's readily available to most first world residents, with the usual methods of rationing. (wait lists for years in European countries, the usual insurance scam in the USA)
A rational human would yes, buy space in a bunker and do all of their work remotely. There would be many variations of commercially available bunkers and security products, and the recent pandemic has showed that many high value jobs can be worked remotely.
