Huh?  Bitcoin is changing more rapidly than probably any industry I can think of.  Just in the past 6 months we've seen massive changes.  You know all those large-scale thefts / hacks we kept hearing about?  We don't hear about those too much anymore, right?  That's because the entire architecture of systems has changed, making it much, much more difficult to pull a massive theft off.

This will lead itself to people becoming more comfortable trusting bitcoin, which will lead to additional solutions and innovations, and round and round we go until soccer moms are paying their babysitter with bitcoin via their iPhone.  There's still loads of work to be done, but don't kid yourself, Bitcoin is humming along at a nice pace.
