This is interesting. Almost like dredging a swamp.

If you can really test an entire city in ten days, and then superimpose the test results on the WeChat social & proximity graph, you can identify hidden disease reservoirs.

Conceptually similar to this graph, but with 11M nodes
Total testing makes the virus visible.

The social and proximity network defines the graph. The green, yellow, red color code at time T1 defines each node’s reported status. And the most recent test result updates the color on that node at time T2.
If you could really do total testing of the population, whether with logistics or something paradigm-shifting like diagnostic-grade wearables, the virus suddenly becomes visible.

Disease reservoirs seen on a screen as clusters of yellow & red codes.
Sufficiently advanced execution is indistinguishable from magic.

If you can innovate in the physical world at literally 100X the pace or scale of others, new tactics become possible.
What the Chinese are trying to do is like dropping an absolutely massive number of flares to light up the entire social graph.

The virus lives in people. Make viral reservoirs visible & centrally quarantine the positives. Repeat till no more reservoirs. Then on to the next city.
