Dr. Ariel Zeleznikow-Johnston discusses longevity trade-offs across species, the evolving definition of death, and the scientific plausibility of revival technologies like cryopreservation and brain uploading. He explores philosophical questions of consciousness and personal identity in the context of future medical advancements.
Actionable Insights

1. Investigate Specific Fixation Providers

If facing a terminal diagnosis and seeking preservation, investigate companies like Oregon Brain Preservation or Nectome (if offering commercial services), as they specialize in fixation-style procedures that offer high-quality structural preservation, which is preferred over traditional cryopreservation methods.

2. Choose Fixation-Based Preservation

Opt for fixation-based methods using chemicals like aldehydes for tissue preservation, as they provide superior structural integrity of the brain without shrinkage or dehydration damage, making them compatible with future uploading or biological revival technologies.

3. Challenge Palliative Death Philosophy

Recognize that societal acceptance and normalization of death often stem from a “palliative philosophy” developed when no alternatives existed. Challenge the notion that death is inherently good or necessary, considering that most terminally ill patients still express a strong will to live.

4. Advocate for Longevity Options

Support the development and availability of technologies that offer individuals the choice to live longer, rather than being forced to die. This respects personal autonomy and aligns with the observed strong will to live across different age groups and health conditions.

5. Prioritize Psychological Continuity

When considering what constitutes a person’s survival or identity, focus on the continuation of psychological properties such as consciousness, memories, personality, goals, and desires. This perspective helps in understanding how identity might persist through future medical advancements.

6. Address Longevity Challenges Proactively

Acknowledge that extending human lifespan would introduce new societal and environmental challenges, but view these as addressable problems with solutions more palatable than the involuntary death of millions. Actively seek solutions rather than using potential problems as reasons to reject longevity.

7. Work Towards a Flourishing Future

Recognize that the success of future revival technologies depends on creating a flourishing future where society has the capacity and desire to restore preserved individuals. This provides an impetus to actively work towards solving current challenges and ensuring a better world for future generations.

8. Cultivate Stronger Future Connection

Develop a stronger connection to the distant future by taking seriously the possibility of living in those times. This perspective encourages individuals to view their current actions as having a real and personal influence on future generations and the world they might inhabit.

9. Adopt Optimistic Medical Outlook

Recognize the historical trend of groundbreaking medical and scientific advancements over the past centuries. Use this precedent to maintain an optimistic outlook on future progress in treating currently incurable diseases and extending human lifespan.
