Transhumanism in one framework: the “three supers”
Chris opens by setting expectations for a wide-ranging conversation on transhumanism. David defines transhumanism through three core goals—boosting intelligence, extending lifespan, and radically improving well-being—while noting possible additions like enhanced empathy.
- •Transhumanism has no single “sacred text,” but has common aims
- •The “three supers”: superintelligence, superlongevity, superhappiness
- •Superempathy as a potential fourth “super,” arguably part of full-spectrum intelligence
- •Transhumanism as a practical future-facing project, not a culture-war topic
- 4:21 – 5:54
Superlongevity and the emotional reality of anti-aging breakthroughs
The discussion turns to radical life extension and how people react to the idea that future generations may not age or die. David notes the psychological and ethical tension of progress arriving “just after” someone’s lifetime.
- •Aging and death aren’t treated as immutable laws by transhumanists
- •Life-extension optimism can feel cruel if it excludes people alive today
- •Longevity research is converging across fields (e.g., genetics, biotech)
- •Transhumanism frames anti-aging as both plausible and desirable
- 5:54 – 8:02
Cryonics and “cryoethanasia”: pausing death until medicine catches up
Chris asks for clarification on cryonics-related terms. David explains the premise—preserving a person to prevent irreversible information loss—while acknowledging major practical uncertainties and introducing the provocative idea of elective earlier suspension.
- •Cryonics aims to preserve the brain’s information for future revival
- •Key uncertainty: whether deterioration before freezing is already too advanced
- •Information destruction is hard in physics, but biology adds complications
- •“Cryoethanasia” as a speculative option: suspension before severe decline
- 8:02 – 9:42
Superhappiness and the hedonic range: from “-10 to +10” to “+70 to +100”
David introduces the idea that our current emotional bandwidth may be radically expandable. He argues the most urgent priority is reducing sub-zero states like depression and anxiety rather than chasing fantastical peak bliss.
- •A simple model of hedonic range (negative to neutral to positive)
- •Civilization could be engineered to operate far above today’s peak experiences
- •Evolution optimizes for genetic fitness, not happiness
- •The hedonic treadmill keeps many people chronically dissatisfied
- 9:42 – 13:19
Editing the genetic “source code” of suffering: screening, selection, CRISPR
The conversation centers on a core claim: eliminating severe suffering requires biological and genetic intervention. David argues prospective parents will increasingly be expected to use embryo screening and eventually gene editing to reduce risks and raise well-being traits.
- •Environmental improvements help, but biology sets strong constraints
- •Preimplantation genetic screening vs. genome editing (CRISPR)
- •Future norms may shift: “natural” conception seen as irresponsible by some
- •“Loading the genetic dice” for higher well-being and resilience
- 13:19 – 18:56
Why the idea feels unsettling: eugenics echoes, sci‑fi memories, and risk analysis
Chris describes a visceral unease about engineered reproduction. David agrees caution is warranted, noting people map the future using cultural references (Gattaca, Brave New World, Skynet) and historical abuses like eugenics, but insists the moral case against ongoing suffering remains.
- •Public fear is shaped by historical eugenics and dystopian narratives
- •Imagination of the future often draws on half-remembered sci‑fi
- •Need for exhaustive risk–reward analysis and governance
- •Claim: without genetic solutions, large-scale suffering persists indefinitely
- 18:56 – 20:59
The Hedonistic Imperative & Abolitionist Project: a moral mission to end suffering
David explains his 1995 manifesto and the broader abolitionist aim: using biotechnology to eliminate suffering in humans and non-human animals. He frames this as moral urgency rather than shallow “hedonism,” and links it to his negative utilitarian ethics.
- •“Hedonism” is used as a catchy label, but the intent is moral seriousness
- •Abolitionist Project: eradicate suffering across the living world
- •Negative utilitarian priority: end suffering first; extra happiness is a bonus
- •Vision of futures where even “lows” exceed today’s peaks (speculative)
- 20:59 – 27:55
Practical pathway: pain thresholds, hedonic set points, and conservative advice today
Chris asks how the strategy might begin in the real world. David discusses near-term levers—selecting for higher pain thresholds and higher hedonic set points—while cautioning about unknowns and noting that basics like sleep, exercise, and nutrition still matter most today.
- •Early interventions could target genes influencing pain sensitivity (e.g., SCN9A)
- •Hedonic set point: people vary in baseline well-being; some alleles correlate
- •Concern: unintended consequences (e.g., empathy effects of altered pain)
- •Drug-based mood enhancement has pitfalls; basics often outperform “hacks”
- 27:55 – 33:53
Do we need pain? Hedonic gradients vs. “blissed out” dysfunction
Chris challenges whether pain is necessary for safety and motivation. David argues adaptive behavior depends on gradients and information signals, not on suffering itself, and cites case studies of unusually high pain thresholds and naturally elevated well-being.
- •Complete painlessness can be dangerous; high thresholds may be workable
- •Case study: Jo Cameron and mutations affecting anandamide (“bliss molecule”)
- •Motivation can persist (or improve) with higher well-being via gradients
- •Distinction between functional bliss and incapacitated intoxication
- 33:53 – 39:07
Mind uploading, the hard problem, and the binding problem: why computers may be “zombies”
Chris asks why not skip biology and upload minds. David argues this runs into unresolved problems of consciousness and phenomenal binding, and he doubts classical digital computers will become sentient—casting skepticism on near-term mind uploading.
- •Hard problem: why consciousness exists at all (vs. philosophical zombies)
- •Binding problem: why many parts form a single unified subject of experience
- •Skepticism that classical digital computation yields sentience
- •Implication: mind uploading into standard computers may not preserve consciousness
- 39:07 – 52:20
Three models of superintelligence and the ethical urgency around animal suffering
David distinguishes three competing visions of superintelligence: enhanced biological post-humans, full human–machine merging, and software-based recursively improving AI (Bostrom/Yudkowsky/MIRI line). He then pivots to what he sees as a present-day moral emergency: ending factory farming via policy and cultured meat commercialization.
- •Model 1: biologically upgraded humans + narrow AI augmentation
- •Model 2: Kurzweil-style merging, potentially including uploading
- •Model 3: software recursive AI with potentially orthogonal values
- •Non-human animal suffering (factory farms) framed as a vast moral catastrophe
- •Near-term solution emphasis: in vitro/cultured meat to accelerate change
- 52:20 – 54:22
Where to learn more: HedWeb and transhumanist resources
Chris asks for recommendations for listeners who want to explore further. David points to his long-running site HedWeb as a hub for essays, links, and arguments related to the Hedonistic Imperative and transhumanism.
- •Recommendation: hedweb.com as a curated “motherload” resource
- •Includes manifesto core ideas plus links and Q&A content
- •Acknowledges some material is dated but still foundational
- •Wrap-up and invitation to revisit as the field develops
