I guess the headline here isn't that these plucky scientists managed to stick a bunch of cameras together, but rather the Chinese state can stick one of these in a crowded area and instantly identify everybody within it.

these plucky scientists

I assume you used that word sarcastically?

   From Wiktionary:

   plucky (comparative pluckier, superlative pluckiest)

     Having or showing pluck, courage or spirit
     in trying circumstances.

   Synonyms

    brave
    spunky
    feisty

I dunno. IMO a "plucky" Chinese scientist would be one who would refuse to work on something as dystopian as this.

I think that was sarcasm...
