"Application of the LifeLog abstraction structure in a synthesizing mode will eventually allow synthetic game characters and humanoid robots to lead more 'realistic' lives."
The computer games and porn industries will certainly benefit richly, and may well provide the vast commercial market needed to sustain such an expensive undertaking.

Of course those 'realistic humanoid robots' will come in quite handy when DoD decides to take over the government by systematically replacing senior civilian officials and media personalities with duplicate military automata.
