Statement
Robots still lack the broad manipulation, diagnosis, fabrication, and self-repair needed to maintain a worldship.
Evidence dimensions
- Basis
- observed
- Readiness
- breakthrough dependent
- Confidence
- strong
Assessment rationale
NASA and GAO surveys describe task-specific servicing, inspection, fabrication, assembly, robotics, and autonomy efforts while documenting limited demonstrations and separate development paths. No cited system integrates broad manipulation, diagnosis, fabrication, qualification, installation, and self-repair sufficient to maintain a worldship.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
An independently replicated robotic system that diagnoses unfamiliar failures, manipulates diverse damaged hardware, produces and qualifies replacements, installs them, restores its own tools and sensors, and repeats under realistic habitat constraints would raise readiness. Narrow demonstrations would change only their declared task boundaries.
