Inside the DJI teardown: Sarah Guo says Shenzhen's manufacturing knowledge can't be scraped into a model

Arena Physica teardown-analyzed a 2019 Mavic Mini and a 2023 Mini 4 Pro under a bench microscope to ask whether the US could build a DJI. Sarah Guo's takeaway: what Shenzhen 'knows' isn't written down or ingestible into a model — it's millions of manufacturing stories stored in people, plus a pace of knowledge-rich adjustment that keeps costs down and yields high. Recovering it requires working with people who have brought up production lines and rebuilding that talent ecosystem domestically; clever data-capture ideas alone won't do. 'America needs to solve the other half of reshoring.'
