Truly fascinating [and equally chilling]. Reading this, I'm reminded of an article by Bill Joy in WIRED from 20 years ago:

"What was different in the 20th century? Certainly, the technologies underlying the weapons of mass destruction (WMD)—nuclear, biological, and chemical (NBC)—were powerful, and the weapons an enormous threat. But building nuclear weapons required, at least for a time, access to both rare—indeed, effectively unavailable—raw materials and highly protected information; biological and chemical weapons programs also tended to require large-scale activities.

The 21st-century technologies—genetics, nanotechnology, and robotics (GNR)—are so powerful that they can spawn whole new classes of accidents and abuses. Most dangerously, for the first time, these accidents and abuses are widely within the reach of individuals or small groups. They will not require large facilities or rare raw materials. Knowledge alone will enable the use of them."

Further, I'm reminded of Damien Broderick's book, "The Spike", also from ~20 years ago.

[Truly shocked to recall those works from so long ago ... encouraging to see there's not TOO much dust in the "attic" - yet.]

Always interesting to see themes churn and develop over time.
