The presidency's fun to think about, but the stuff that will REALLY blow your mind is when you consider how he set up Crash 2.0 and the Wireless Matrix.
Don't think so? Consider this line of thought:
The Big "D" bequeaths all those Renraku shares to Miles Lanier. Miles & Richard Villiers then use that to set up a "falling out", so that Miles is considered trustworthy by Renraku. In the process of this long con, Miles and Richard are able to gut both Renraku and Fuchi, setting up Novatech to be the newest AAA corp on the market. But the process of creating the corp leaves Villiers strapped financially, so he has to go "public" with shares in Novatech, creating the biggest online transaction/presence/event EVER. This becomes a target of AIs, Terrorists and everyone else. After the Crash, technomancers are born and AI's become more prevalent.
Ipso Facto, Dunkelzahn created Technomancy.
