As this Guardian article says, (and I think it describes the primary aim of the BBP quite well):
[reverse engineering the brain] will help us in

'determining how the brain works could help with treatment of diseases while providing clues for designing artificial intelligence'.

IMHO, clues don't make an AI, but they take us one step closer to it. We don't even know whether a cellular resolution is good enough to get any meaningful results from the simulations (which are on a cellular level and simulate electronic signals without considering anything on a molecular level), but its better than doing nothing. The BBP itself is expected to last around a decade, so after a decade (2017) we will have gathered some clues about how a mammalian brain functions.
