Over its history, ARPA became DARPA and then quickly transitioned into a purely political dole-out program for whacky leftist ideas (e.g., the DARPA head job is a political patronage position.) There are/have been good things to come out of DARPA that benefit us, but there are more whacky nothing-comes-of-it programs.
Some evil stuff as well. The head of DARPA during Obama’s admin was into “biologicals”. Makes one suspicious.
