A Kessler event destroyed any overhead data collection for everyone at the onset of the Conflict. As resources dwindled, costs rocketed, and time became critical, fully mech/comp units were wasteful and their loss was a heavy burden. Wetware integration had been standard, so wettech was the natural evolution from doubleplus need. Mobile Foetal Units were prioritywise needed to gather data behind enemy lines. Foetal processors saved thousands of manufacturing hours at 1/14th the resource cost.
