Visionaries?

Concerning a recent article I read about the Fermi Paradox:

The simple explanation could very well be correct: life is too stupid to survive. We may reach a certain level of technology and then invariably self-destruct.

My view on this is our own mortality virtually guarantees extinction in a self-similar way. Who cares (very much) about a hundred years from now? If tomorrow they revived some dog that had been frozen without damage it might change everything. We might then be like the salmon of the galaxy that make it upstream. If death was no longer certain would we not then have a reason to focus and combine in a collective effort to reverse aging and travel to other stars?

It is discouraging that even supposed “visionaries” like Musk and Bezos do not understand this.
