Summarised by Claude from recommending comments
When pioneering marine biologist Dr. Ha Nguyen is offered the chance to travel to the remote Con Dao Archipelago to investigate a highly intelligent, dangerous octopus species, she doesn't pause long enough to look at the fine print. DIANIMA - a transnational tech corporation best known for its groundbreaking work in artificial intelligence - has purchased the islands, evacuated their population and sealed the archipelago off from the world so that Nguyen can focus on her research. But the stakes are high: the octopuses hold the key to unprecedented breakthroughs in extrahuman intelligence

on “Ask HN: What are you reading?” ↗In the sci-fi novel "The Mountain in the Sea" (highly recommended btw) there is a piece of tech called "abglanz" which is an identity shield mask that flickers in iridescent blurry patterns to protect a person's privacy from camera surveillance.
