Bob Kahn je mdr. soavtor protokolov TCP in IP, pionir omreževanja. V DARPA postal kasneje direktor IPTO (Informational Processing Techniques Office), kjer je ustanovil milijardo-dolarski projekt Strategic Copmuting Initiative, največjo investicijo ameriške federalne vlade v računalništvo ever ('83 do '93) - razvijali so proizvodnjo čipov in umetne inteligence. Ustrašili so se japoncev, podobno kot v 50ih sovjetov.

Preko očeta v sorodu s fizikom Hermanom Kahnom, ki je napisal knjigo o tem kako bi amerika lahko zmagala nuklearno vojno in postal inspiracija za dr. Strangelove-a v znanem Kubrickovem filmu. Ustanovil je Hudson institut, konzervativni think tank ki je začel pri premišljevanju hladnovojnih scenarijev in se razširil na polja ekonomije, zdravstva, šolstva in gemblanja. Delal je tudi v RAND korporaciji, močnem hladnovojnem inštitutu, vpletenem v vietnamsko vojno, iraško vojno, danes pa kuri "AI apokaliptični" scenarij.
