Means “advanced human”. It is used for people with super-human abilities because of the power of technology. People with super-human prosthetic arms (such as the ones from Psyonic) can be called Homo provectus. In the future, advanced armor, mech suits, and cyborgs can all be called Homo provectus.
That prosthetic arm isn’t just Homo sapiens, it’s Homo provectus.
