This talk provides a speculative contemplation of philosophical topics that might arise with brain-machine interface technology and explores the new ways that individuals and society might self-enact as a result. Brain-machine interfaces that could be pervasive, continuous, and widely-adopted suggest interesting new possibilities for our future selves. From a philosophical perspective, these possibilities concern the definition of what it is to be human, our current existence and interaction with reality, and how all of this could be dramatically different in a scenario of digitally-linked cloudmind collaborations. This talk looks at some of the foundational ontological questions of how the progression of the existence of the classic human might evolve. Perhaps the most pressing question that currently-minded potential adopters have is how to avoid getting irreparably pulled into a groupmind. To protect against this, there could be an expansion and letting go of the term and concepts of personal identity, and humans as a unit of organization, in favor of instead self-relying on a decentralized permissioning structure like blockchain technology for managing empowered and resilient crowdmind participations.
