The NewSpeak article is 4 years old, and ... no "transhumanism"? Maybe the NewSpeak article is clickbaity hype, and DARPA was busy with other things (e.g. the effort to find platforms for fast responses to disease epidemics that produced the monoclonal antibody treatment for Covid being distributed by Eli Lilly for nearly a year).
Maybe AI was new to NewSpeak in 2017, but people in tech know AI has been a "thing" among tech industries for 3 or 4 decades. Borrowing the title of an Andrae' Crouch song, "It Ain't No New Thing".
