Excellent video (direct link) thanks for that, a must watch:
“…solving the anonymity and privacy issue [for bitcoin] is something we need to solve before the protocol ossifies because we won’t get too many chances, otherwise we will succeed in disrupting the financial services infrastructure with bitcoin, and a decade from now we are going to need to disrupt bitcoin with something else…”.
Offtopic: It can be argued that bitcoin has already ossified and it will be very difficult to tack on core privacy features at this point, so… the decade is waiting for Safecoin already 
. My concern (still) is this mistake might be repeated by leaving the Safecoin divisibility issue until after launch, that may also be too late:
- -ve : Early on when the network is small it possibly can’t handle division transaction load so division is not included.
- +ve : Few players so the core code can still be changed easily by core Maidsafe team without needing consensus.
- +ve : Later on when the network is large it can handle division transaction load
- -ve : Many players paticipating in larger network means the core code/protocols cannot be changed easily without requiring consensus. The network has “ossified”.
