I've written before about the differences between clever algorithms and approaches to AI which use massive data volumes as their core MO. Philipp Lenssen over at Google Blogoscoped has a great example of this supplied by Google's spell checker. Typing in 'she invented' returns the spelling suggestion 'he invented'. Other examples surface in the comments. There is a nice irony here. I used Schmidt's claim that the Google spell checker was a form of AI as an example of why Google's centrality in the public's perception of AI is a sort of tragedy.
An issue that came up in the Future of Search event (about which I'm attempting to write a longer piece) is that of correctness (the term precisiation came up...). You search for some information and get a page that makes a statement of the correct form, but is it correct? Some great examples flew about regarding claims of the origin of various electrical applications and the names of Edison and Tesla. The problem is that the majority vote may not always be correct.
