Recursive Self-Improvement
The AGI Bootstrap: PLTM learns how to learn better.
Uses discovered universal principles to improve PLTM itself:
1. Analyze PLTM's own performance
2. Discover improvement patterns
3. Apply improvements
4. Measure results
5. Recurse
This is the meta-learning loop that enables unbounded improvement.
