Top line: A thin Saturday: robotaxi economics got its scaling memo — the constraint isn't driving ability, it's fast local vehicle servicing — while Amazon's million-robot milestone recirculated and the rest was stunt videos and stock pitches. Two items, honestly short.
The robotaxi scaling problem: from 14 cities to 15,000
- What happened: The Robot Report: robotaxis have proven driving ability across ~14 cities; scaling "globally" to the tens-of-thousands range runs into the unglamorous constraint — fast, local vehicle servicing (depot density, technician networks, parts) rather than autonomy performance.
- What's genuinely new: the constraint named. The robotaxi record is all capability claims and city counts (Wayve: Tokyo by year-end, Mercedes production deal; <10k robotaxis worldwide vs ~100M cars/yr); this piece argues the bottleneck is the boring layer — the same "robot aftercare" thesis the humanoid side is learning from maintenance economics. Unthreaded (analysis, not news); watch for the servicing-infrastructure market forming.

Amazon's million-robot milestone, recirculated
- Market commentary (Jesse Cohen, tradersunion) frames Amazon operating over 1 million warehouse robots, "each robot able to replace 25 workers." The fleet number is the established milestone; the 1-to-25 ratio is commentary, not Amazon's. Recorded as the installed-base color next to yesterday's $100M Indiana plant item — the largest robot fleet on Earth is Amazon's, and it's still growing by integration rather than humanoids.

Dropped
- Robot-dog marathon on one charge (South Korea) — an endurance stat without a deployment fact; the Knowridge writeup adds nothing to the Sep 25 items.
- Beijing humanoid obstacle-race stumble (German recirculation of the Sep 21 event) — the spectacle layer, already recorded.
- "Robotics will be the biggest opportunity within the AI supercycle" + dividend-stock pitch — markets noise.
- "PEAI (Physical Emotional AI)" (note.com) — single low-tier self-introduction post; verify before weight if it ever recurs.
