We may think about cyber warfare very differently than China or Russia. Are we making a mistake conceptualizing it as a space in which we can maneuver, and thinking of exploits as digital bullets? Jonathan argues it may make sense to think of cyber warfare in more tactical terms, and questions whether a true strategic shock like the surprise attack on Pearl Harbor is likely in cyber. 

The​ ​Log4j​ ​vulnerability​ ​has​ ​a​ ​theoretical​ ​reach​ ​into​ ​anything​ ​made​ ​with​ ​Java.​ ​Are​ ​there​ ​other​ ​old​ ​but​ ​reliable​ ​tools​ ​in​ ​software​ ​design​ ​that​ ​hold​ ​hidden​ ​risk?​ ​And​ ​will​ ​patches​ ​work​ ​if​ ​they​ ​threaten​ ​software​ ​functionality?​ ​How​ ​the​ ​Log4j​ ​vulnerability​ ​was​ ​identified​ ​and​ ​whether​ ​we​ ​can​ ​count​ ​on​ ​this​ ​defense​ ​in​ ​the​ ​future.​ ​

Should we be worried that the most advanced integrated circuits come from Taiwan, one of the most threatened places in the world? Jonathan outlines photolithography and other techniques that define the world’s most sophisticated chips, and where cyber-attackers would focus their malevolent efforts on hardware. Christian asks whether quantum computing will be real anytime soon.
