[The Matrix] Where did they get the memories/files/whatever they needed to upload things like kung fu or helicopter pilot to people's brains?

Did they have to liberate someone who knew kung fu, or hack the brain of someone still in the matrix? And does that mean that all the free people know the same kung fu, and thus have the same weaknesses that could be exploited?

Since the machines are the ones that truly created Zion, along with the last few iterations of the city, we can assume they provided the new "free" humans with all of the technology needed for them to thrive in accordance with the Architect's design.  This includes memory files for Kung Fu and flying helicopters.

All free humans will have the same baseline set of skills, but will be differentiated by the presence of human free will.  Something that transcends programming, and unbalances the Architect's equation.
