This is such an interesting thread, and a lightning tour of what advanced manufacturing tools look like today, from industrial robots to lasers. (As a side note, this is also very old-school, now mostly lost, Twitter, where experts put together long threads on narrow topics)
Impressive & important paper is able to get at the role of power in health care by looking at the military, where the ranks of doctors & patients are known. The powerful get more attention, which also results in better outcomes, at the expense of the less powerful. Good thread.
Interesting thread suggesting a lot of the UFO sightings by the US military are just excusing surveillance by drones. Wouldn’t be the first time UFOs were a cover, the CIA’s secret spy planes were purposely passed off as UFOs (they were over half of all reports in the 50s & 60s!)
