Lot of issues here but one part that sticks out in light of the almost-attacked-a-Chinese-ship story today: people with very important jobs where lives are at stake have bought the hype and outsourced their whole brains to AI. We're going to see more and more of this. www.cnn.com/2026/09/18/p...
In the past year, the Defense Department has rapidly made Maven a cornerstone of the US military apparatus. Several former senior US military officials now work for Palantir, including some with high-level security clearances in Centcom’s Tampa headquarters. Their role is to keep the software functioning inside secure military environments. Some Centcom personnel expected Maven to flag stale information or inconsistencies in the underlying intelligence assembled for potential targets, the officials said. It’s not clear why they had such expectations.
The intelligence report, circulated across the US military this spring in the midst of the war with Iran, immediately set off alarm bells: A Chinese ship in the Middle East was transporting components of a nuclear weapons program.

The US military swung into action with plans to intercept the vessel, according to four sources familiar with the episode. According to two of the sources, armed members of the US military were preparing to board the ship. Military planes were in the air, one of those sources and another source familiar with the incident said.

It was only just before the planned operation that officials dug deeper into the report put together by a special operations command analyst and found it had been generated with the help of artificial intelligence (AI) — and that a chatbot the analyst had used inaccurately identified the material the ship was carrying. CNN was not able to learn what the misidentified cargo was.
