A prosthetic limb can restore movement. A neural interface could help someone communicate. Technologies designed to expand human capability raise a question that product specifications cannot answer: who retains authority over the person using them?
Herbert Sim’s Human-Sovereignty Transhumanism places that question at the centre of technological progress. His philosophy supports efforts to reduce suffering and overcome biological limitations while insisting that individuals retain control over their bodies, minds, identities and personal information.
For technology founders, the argument introduces a measure of success. A product’s value depends on the freedom its users retain throughout their relationship with it, alongside the abilities it provides.
Bodily autonomy is the starting point. In Sim’s account, accepting an enhancement should never transfer authority over a person to its manufacturer, an employer or a government. Decisions about intervention require informed, voluntary consent, with understandable explanations of risks, limitations and obligations.
Consider a hypothetical connected prosthetic that depends on proprietary software. Its user would need to know whether essential functions could be restricted remotely, what happens if support ends and which maintenance options remain available. Those questions belong in the design process.
Neural privacy brings the same principle into more intimate territory. HST argues that information generated by the brain deserves meaningful protection and individual control. A device’s capacity to interpret neural signals does not establish permission to collect, commercialise or manipulate them.
The distinction matters even when a system serves a beneficial purpose. Helping someone communicate should not require unrestricted access to unrelated information. For developers, this suggests limiting collection, explaining intended uses and making access permissions understandable.
Voluntary enhancement also requires a meaningful right to refuse. Sim challenges the prospect of technological modification becoming an unofficial condition of employment, education or social participation. A choice loses substance when declining it carries penalties that people cannot withstand.
Imagine a workplace offering cognitive enhancement while reserving promotion for participants. Signing a consent form would reveal little about the pressure behind that decision. HST asks businesses to examine the circumstances of consent as carefully as the document recording it.
The right to disconnect extends that scrutiny beyond initial adoption. Users should retain meaningful ways to withdraw permissions or leave connected systems. Where immediate disconnection could threaten health or essential function, safe transition and continuity require attention from the outset.
These arguments extend Sim’s Cypherpunkism from control over money and information to authority
over the human person. Digital sovereignty asks who controls an account, an asset or a communication channel. HST asks what happens when comparable dependencies reach into bodies and minds.
The analogy has limits: biological systems require safeguards that cannot simply be copied from cryptocurrency. Nevertheless, both arguments favour practical control, informed participation and alternatives to dependence on a single authority.
HST offers a philosophical lens for evaluating innovation, rather than proof that any particular technology is safe. Its challenge to entrepreneurs is concrete: build products that expand capability while preserving the user’s power to understand, consent, refuse and leave on terms that protect their dignity.
