They are nowhere near this and I highly doubt that even the next 15-20 years will bring around any type of technology like this.
Google is a machine, and the way it works is very similar to the CTRL+F find function in most document editors (Notepad, Word, etc.) It can find exact instances of your search term and about as smart as Google is, it can also display related terms and misspellings.
However, it is still very basic in the way that it handles data.. Which is why you heard a while back about Google employees actually checking sites manually. Because Google (the algo) is capable of FINDING the term, but how is a machine to know whether or not what its found the term in is legible, or makes sense?
In my opinion, the reason that people end up with garbage spun content is because they don't fully understand the impact of Google
STOP WORDS!
Here's a good list of Google Stop words: http://www.link-assistant.com/seo-stop-words.html
What a stop word is, is a word that basically is completely ignored by Google. And you'd be surprised how many of these words are in your thesaurus!!
{none|not any} of {these|what I'm saying} {is|will be} {seen|regarded} as something {we've|I've} made {myself|ourselves}.
Every single one of those words is a stop word. So no matter how you spin that sentence, no matter how that sentence ends up... It doesn't matter to Google, because in its mind, those words are useless and mean nothing.
So if you are spending your time deciding between {I have|I've|I tend to} etc, stop. Because your time is being wasted, Google does not give a shit how you refer to yourself, it cares about the remainder of your content.
Another crafty way to unique up your content is through punctuation.. Google does not read punctuation, but it surely knows that it's there. For example...
"thank you for your time dr"
"thank you for your time, dr"
"thank you for your time, dr."
and even
"
[email protected],your;time:dr?"
are all pretty much the same. Why? Because Google is a machine. And in order to FIND THE TERM, it must disregard the punctuation. Why? Because Google is a machine and does not understand the CONTEXT in which the term is being used!
All it knows is "ok, I've located the search term here.. To the left is this other term, the two are relevant to each other. 4 sentences in, I've found another term, relevant to the previous 2... etc. etc."
It does not know, "oh, wow, what a great article about fruit bats. I love how it's all laid out and their grammar is perfect! This definitely deserves top spot."
