So Siri in Apple iphones (2011) is not a scale big enough?
How about Cortana in windows? (2013)
Or How about Google glass? (2013) Remember, "Okay Google" voice commands?
Or How about Nuance's Voice recognition (Started in 1997 and updated all through present).
I will ask again, whats your definition of "Mature Technology"?
Also, What is the meaning of unprecedented scale?
How do you measure accuracy? What is your criteria of accuracy? What do you call accurate?
Do you know the meaning of Recall and Precision in recognition system?
Here is a precision recall curve of Eigenface.
You can choose your precision to be 99.9% if you want by limiting recall to 50%.
Do you know which was the first "popular" "Big Data" application? Do you really?
Ever heard of inverted index calculation? Relevancy calculation?
Hint : "Big Data" has been in use since early 2000. For a very very well known and vast scale problem. And no, even the term "Big Data" or its hype goes back to 2005 or so with release of BigTable object store by Google. All of these things are 20 years old at least.
Once again you don't know what you are talking about.
So you are using the technologies such as siri, cortana which simply piggy backed on the system being sold globally? that's not exactly adoption, but companies pushing technologies through the channels due to massive dominance of their own platforms. Big data, AI, voice recognition had been around for a long time, but it only started accelerating in the last few years due rapidly lowered cost of memory, which enabled acceleration of AI development in the last few years. So again, what you said doesn't contradict what I just said.
