- A GPT-4-generated gene-therapy protocol was shared that outlines how to re-engineer ceruminous (ear-wax) glands so they can secrete wax at arbitrary anatomical sites; the full plan is available at https://gist.github.com/Epivalent/ea7461ed9c87eb561b8c86c17d9bb3cc/raw.

- A 2 300-page robotics/nanosystems textbook (https://dl.icdst.org/pdfs/files3/fef0590f02fa06bb42cba558fbc9e51c.pdf) was recommended as foundational reading for anyone entering the field.

- Community advice for hands-on learning: build your own servo/actuator from scratch and physically “wrestle” the motor shaft while implementing a PID controller to gain intuitive control-theory understanding.

- Auto-tuning PID algorithms were highlighted as a next-level challenge once basic servo control is mastered.

- State-space modeling was singled out as a topic “about to become extremely important,” suggesting it should be prioritized in upcoming robotics and control-systems work.
