Optimus labor; longevity claims kept cautious
Musk’s endgame is a multiplanetary civilization. Optimus as harsh-environment labor fits his narrative. A “300-year lifespan” is not a core public commitment of his companies.
Odds (editorial): Low (10%)
What Musk / companies have said
Self-sustaining Mars cities (long-term million-person talk exists) are central. Robot labor to expand bases is sometimes linked to Optimus. No Neuralink/SpaceX roadmap promises 300-year life.
Our probability read
Persistent multiplanetary outposts this century: hard, still his true north (low–medium). Machine labor filling in: narratively medium if tech lands. 200–300 year lifespans: very low under known medicine; not the center of Musk tracking. We do not assert 300 years—only flag extreme longevity as speculative sci-fi adjacent.
What we track
Mars population vs resupply, space Optimus, any longevity remarks.
