Episode notes
Sustainability As A Design Constraint
- Robby frames sustainability as a design constraint: every repo or tool is a promise to your future self to maintain it.
- Treating maintenance as a primary concern shifts choices toward long-term viability over short-term novelty.
Most Work Is Maintaining Existing Systems
- Most developers spend their careers iterating on existing systems rather than building greenfield products.
- Recognizing software work as maintenance reframes it as valuable infrastructure work, not second-class craft.
Decide If You're Experimenting Or Shipping
- Decide early whether a project is an experiment or something you’ll ship and maintain, then constrain scope accordingly.
- Set a minimum viable releasable version to force completion and avoid accumulating unfinished experiments.
