A very interesting topic. One of the many human misteries and obsessions.
The Terracota Army is probably one of the most impressive archaelogical findings, one that speaks volumes of the extent humans can go to attache themselves to life and power.
I guess we'll achieve it someday, at least the ones in a possition of power and wealth.
If the average folk may find themselves begging for some more years to enjoy with friends and family, to finish personal or family projects, imagine how much longer the rish and powerful would want to live.
One average life is enough for me. I don't think humanity has changed in the thousands of years we have been registering its history. Everything suggests things will only get worse in the future, why would anyone want to witness such disgrace. :)
At the personal level, it may be cool to see generation after generation of your descendants, but if they turn out bad, I don't think it will be that fun. Besides, sooner or later they'll get tired of ancient grandpa'. Maybe they'll find some old fashion mercury and put it in his coffee.
I think that those who have "achieved" immoratality have done it by sheer will power. The great men and women of letters, the grreat thinkers of old and the current people creating and suggesting ideas to transform the world (not always for the better). Fame and infamy are equal sources of immortality.
I guess, if what is said about the blockchain is true and if a 3rd WW does not obliterate us from the planet, we all are in a way immortal already. If all we post here will be here for good...
