It is all playing out exactly according to the script. It is amazing how reticent large firms are to even investigate the possibility that they are not the light at the end of the tunnel but the deer in the headlights.
http://en.wikipedia.org/wiki/Disruptive_innovationWhat they have shown is that good firms are usually aware of the disruptive innovations, but their business environment does not allow them to pursue them when they first arise, because they are not profitable enough at first and because their development can take scarce resources away from that of sustaining innovations (which are needed to compete against current competition). In Christensen's terms, a firm's existing value networks place insufficient value on the disruptive innovation to allow its pursuit by that firm. Meanwhile, start-up firms inhabit different value networks, at least until the day that their disruptive innovation is able to invade the older value network. At that time, the established firm in that network can at best only fend off the market share attack with a me-too entry, for which survival (not thriving) is the only reward.[3]
I would say that if threatened encumbents do not have a bitcoin strategy by now/soon they are destined to become obsolete.
