I wonder how many people will continue to use the feature after its initial, relatively useless release, and notice if and when Google gets to the point where it's functional enough to be usable - let's say it's only wrong 1% of the time, so it gets some menus 100% correct.
In my experience, vendors who release new features at this quality level essentially never announce "Heh folks, we've fixed it; you should come back and try it again". There are Google features that were at least as useless as this one at first release, which I never use, because I "know" they don't work. Every once in a while some youngster tells me that they use the feature, and find it usable and convenient, and I look back and realize it's been years since I tried it.
One example is Google Translate. When I last used it, its many flaws included the practice of omitting words it didn't understand, without any ellipsis. It only took one example where the word omitted basically meant "not", reversing the meaning, to cause me to file Google Translate as "useful ONLY if you basically already understand the text". I relatively recently discovered it's now good enough that people with no language in common routinely use it to communicate on MMORPGs; another player wondered why I wasn't interacting with an in-game neighbour whose chats always used the Cyrillic alphabet, and didn't think "because none of the languages I know use that alphabet" was a reasonable response.
