If I go to a talk about a piece of technology, I expect the presenter to have enough experience with it to be able to provide me with a means of determining where I am situated in said technology's landscape, and what frame of reference is required to evaluate how to move about that landscape. It doesn't matter how eloquent and thorough the introductory tutorial is, if the presenter has not experienced the technology sufficiently to have accumulated a few scars[1], they will not have the ability to convey the relative importance of the various aspects of the introduction, with which can be modified simply as a matter of taste, and which should be followed unless very careful consideration of global engineering context, and a full appreciation of the consequences. If you are unable to meet that bar, at the very least, your abstract should make that abundantly clear out of respect for your audience. [1] or at least have the experience to say that normally they would have expected to get bitten by something by their point in usage, but the technology meets their requirements so thoroughly that it has been particularly smooth sailing.
