Its way more than this, today I got it to write some code, and a bit was wrong, I told it why it was wrong and it said oh ok, and toddled off and fixed it - in all the places that were wrong. This is way more than an encyclopaedia could, lossless or not.
The more I use it, the more surprised I am at its capabilities, it really is like a beginner dev, but one that doesn't learn from its mistakes (yet anyway). I find myself asking it to do more and more.
