I've been keeping up with the developments, and IMO this is a fair assessment. This author has every reason to be biased, but I do have the impression that the problems that bitcoin can potentially solve, coupled with the momentum it has gathered, means that it is going to be occupying a real space in the financial sector (and likely others) for some time to come.
For me, the biggest question mark at this point has to do with the development team. It is small, centralized, and the devs carry a weight that grows heavier each passing day. From what I have seen, I am optimistic about them. They seem to be a conservative, thoughtful bunch that are more than willing to speak about the limitations of bitcoin, and the threats to its success. Besides the effect they have upon the code, their ability to manage expectations has a palpable effect on a community. I expect that at least one major hard fork sits between HERE and THERE, and I think they can pull it off.
Personally, I think that bitcoin will do well as a transactional tool within the next couple of years. However, my guess is that it will be most disruptive first in another space, and only at a later point powerfully change the landscape of finance.
