I don’t doubt that the groups at Apple responsible for [other] technologies are comprised of individuals striving to improve things as quickly as possible. It’s hard to say how much the impression of slow progress is due to internal challenges we don’t know about, Apple’s lack of knowledge about the breadth of defects, or the public’s perception being skewed by severity of the impact from problems that persist.
Whatever combination of luck, hard work, and pragmatism is powering the Siri team’s “year of good work,” perhaps it should serve as a model, or at least as a symbol of hope for these teams as they move forward adding features, fixing bugs, and finessing the public’s perception of the value of their work. A world in which every group at Apple somehow achieved the standard of apparent progress that Siri has achieved would be a very good world indeed.
It’s a beacon of hope for me, at least. If Siri can get from where it was to where it is now, anything can.
