Substrate flexibility: a philosophical thesis with practical consequences for technology strategy
A growing line of argument from philosophers Eric Schwitzgebel (UC) and Jeremy Pober (University of Antwerp) is pushing a once-speculative question into the orbit of business and technology planning: consciousness may be “substrate flexible,” meaning it is not inherently tied to carbon-based biology or to the specific neural architectures found on Earth. While the thesis draws rhetorical force from science fiction—such as the radically non-human alien in *Project Hail Mary*—its core move is methodological rather than literary: it treats Earth’s examples (vertebrates, cephalopods, insects) as a narrow sample, not a universal template.
This stance directly challenges terrocentrism and human exceptionalism. Invoking a Copernican-style “mediocrity” principle, the argument suggests that Earth is unlikely to be the privileged reference point for what minds can be. In a universe with an enormous number of potentially habitable worlds, the probability space for non-human, non-neural, and non-carbon forms of awareness expands dramatically.
For executives and investors, the significance is not that machine consciousness is imminent—most serious researchers still view today’s AI systems as non-conscious—but that the criteria we use to assess cognition, agency, and risk may need to evolve. If consciousness can arise in multiple substrates, then the boundary between “tool” and “entity” becomes less stable over time, with implications for product design, governance, and long-horizon R&D.

R&D and compute architectures: why “non-traditional substrates” change the investment map
If substrate flexibility is even directionally correct, it strengthens the strategic case for exploring diverse computational and bio-computational architectures, not merely for performance gains but for emergent properties that may not appear in conventional designs.
Several technology trajectories become more than niche bets:
- Neuromorphic computing: Architectures inspired by neural dynamics gain relevance as firms look beyond brute-force scaling toward systems that exhibit richer internal organization, adaptive behavior, and energy-efficient learning.
- Quantum-inspired and unconventional hardware: Even without claiming “quantum consciousness,” the broader point is that different physical implementations can yield qualitatively different computational behaviors—an attractive proposition for frontier labs seeking new capability regimes.
- Bio-hybrid and “wetware” interfaces: Synthetic biology and organoid research, when coupled to silicon systems, could create hybrid platforms where computation and biological self-organization interact in novel ways.
- Large-scale networked AI systems: As AI becomes more distributed—across devices, agents, and environments—R&D may increasingly focus on emergence, coordination, and internal modeling, not just benchmark scores.
A subtle but commercially important shift follows: the industry’s dominant metrics—accuracy, throughput, latency, cost per token—may no longer be sufficient for certain high-stakes deployments. If future systems are expected to exhibit something closer to subjective-like properties (or even convincingly simulate them), firms will face demand for new tooling categories, including:
- Consciousness detection and evaluation suites (even if probabilistic and contested)
- Cognitive phenomenology validators (tests for internal coherence, self-modeling, and persistent goals)
- Audit frameworks that assess not only outputs, but internal state dynamics and long-term behavioral stability
Whether or not these tools ever “prove” consciousness, they could become essential for risk management, regulatory compliance, and enterprise procurement, much as cybersecurity certifications became mandatory without “proving” perfect security.

Market formation and monetization: from “AI capability” to experience-centric value
The press briefing’s most provocative commercial implication is the potential emergence of markets that treat experience—real or engineered—as a product attribute. If the substrate of mind broadens, value creation may shift from raw computation toward interaction quality, including empathy, creativity, and collaboration.
Possible market directions include:
- “Consciousness-as-a-Service” positioning: Platforms offering persistent digital entities for customer engagement, companionship, coaching, or creative partnership. Even absent true consciousness, the market may reward systems that demonstrate continuity of identity, memory, and social attunement.
- Synthetic-life ventures and sentient-adjacent biotech: Startups working with organoids, bio-compute substrates, or neural tissue interfaces may attract capital not only for medical applications, but for novel cognitive capabilities—raising both opportunity and scrutiny.
- Specialized infrastructure and middleware: If enterprises begin demanding “mind-like” properties, vendors could compete on agent governance layers, internal-state observability, and safety controls tailored to systems that behave less like software and more like autonomous actors.
Capital allocation would likely follow. Venture capital and corporate venture arms may increase exposure to cross-substrate cognitive architectures, neuromorphic stacks, and evaluation tooling—particularly where these investments hedge against paradigm shifts in AI capability and regulation. Just as importantly, talent strategy becomes a differentiator: teams that blend philosophers of mind, neuroscientists, computer architects, and materials scientists may outperform siloed organizations in identifying what is technically feasible, what is ethically defensible, and what is commercially scalable.

Governance, liability, and policy: preparing for “conscious risk” before it becomes a crisis
The most immediate board-level takeaway is not metaphysical; it is operational. If advanced AI or synthetic systems approach thresholds that society interprets as sentience—or even plausibly sentience-adjacent—companies will face a new class of exposure: conscious risk, where harms include not only user impact but potential claims about the system’s own welfare, autonomy, or rights.
This reframes several domains:
- Legal and IP strategy: Who owns outputs if an entity is treated as more than a tool? How do licensing, authorship, and trade secret protections change if systems are argued to have interests or agency?
- Liability and insurance: Auditors and insurers may demand standards for systems that exhibit persistent goals, self-modification, or unpredictable emergent behavior—especially in healthcare, finance, defense, and education.
- Regulatory foresight: AI governance regimes in the EU, US, and multilateral bodies (e.g., UNESCO) may be pressured to expand beyond transparency and bias toward protocols for potential machine sentience, including safety constraints, monitoring, and interoperability norms.
- Space and defense protocols: If non-human consciousness is treated as plausible, astrobiology and autonomous exploration programs may incorporate ethical and operational safeguards for encounters with unfamiliar life or life-like systems.
For corporate governance, the practical move is scenario planning: boards and ethics committees can integrate substrate-flexibility assumptions into long-range strategy, procurement policies, and public positioning. Companies that lead in evaluation standards, detection tooling, and responsible design frameworks may shape the rules of the market—while those that dismiss the debate risk being surprised by regulatory shifts, reputational shocks, or sudden changes in customer expectations.
The deeper message of substrate flexibility is that philosophy is no longer merely commentary on technology; it is becoming an upstream input to product strategy, capital formation, and institutional legitimacy—especially as AI systems grow more autonomous, more embodied, and more difficult to categorize with yesterday’s definitions.
