In my opinion, Siri's faults do not stem from it's lack of profile on me. I rarely say things to Siri like "phone my wife" and it not know who my wife is. It just doesn't need my personal data for what I ask it.
"Apple stores six months of voice recordings to allow its voice recognition engine to get a better understanding of users" - If Apple's stance on privacy meant they wouldn't do this, I could see there being a problem, but they are storing our queries to improve voice recognition!
I think Siri has a far worse rep than it deserves. I even tried asking it "Tell me about the latest Samsung phones". It gives me web results - the top one was a link to Samsung's website. If Apple displayed only the top result, and formatted it like traditional Siri answers, and not like a web search, people would give Apple more credit for Siri's abilities. This seems to be one of Google's biggest advantages with Google Now.
That I have found is its biggest Achilles Heel. I use them all or at least play with them. Unlike Google and Alexa, I will ask a question and I will get a result that wants me to look at a list of web results. The others will speak and answer to me which I can then use or ask a followup question. Siri doesn't give me that. Maybe it's the way I ask. I don't know. I just know the output from Siri is frequently out of wack for the situation.
Note: Siri has been getting more accurate but still lags Google, Alexa, and Cortana by a good bit. JME, YMMV
