There absolutely was. From the chapter you linked, the AIs are already in the infrastructure, because how else the economy collapse happened if the AIs werent an important part of human infra? The AIs were hacking the autonomous mechs too, if they can routinely break such encrypted military networks, humanity was fucked.
Also reminder, the progress of infrastructure projects are usually measured in decades, maybe years if it's a national focus. The chapter all but spelled out that the AIs were THE infrastructure by the time war broke out.
