Preserving Minds by Escaping Biology

Visionaries propose transcending flesh and blood by digitizing brains for software preservation. Uploading consciousness to computers promises near immortality by backing up identity like data. Yet monumental ethical questions give technologists and philosophers alike pause around fundamentally altering the human condition.

Overcoming Mortal Limits

Medical realities from senescence to injury motivate developing backups securing personhood beyond biological viability. Connectomic brain mapping aims to simulate neural architecture with sufficient fidelity to boot consciousness in digital substrates. Subjective immortality beckons if environments emulate physiology dynamics accurately enough.

Monumental Barriers Remain

However, incredibly daunting technical obstacles persist on route to viable mind uploading. Scanning intraneuronal structures non-destructively at nanometer resolutions remains outside computational limits. And software complex enough to simulate consciousness resides generations away. Mainstream application likely exceeds the 21st century.

Asking the Hard Questions

Parallel ethical debates also demand deliberation regardless of timelines. Do uploads constitute the original person or just software copies? Could they suffer differently than biological minds? Will only the affluent gain access to enhanced digital experiences, further privileging the elite? And who oversees the treatment of digital minds?

Reexamining Humanity in an Age of AI

More fundamentally, achieving machine sentience forces uncomfortable questions around what notions make us uniquely human in the first place. If algorithms exhibit creativity, emotion, and intelligence comparable to people, traditional anthropocentric paradigms warrant revisiting as advanced AI assimilates into society.

While immortalizing personal identities via emulation remains improbable for the foreseeable future, steady momentum towards engineering general machine intelligence promises much philosophical soul-searching around intelligence what it means to be human. The answers may radically reshape cultural self-conception in coming generations.
