My background is in talks at technical conferences where the CfP, the infamous "Call for Papers", rules. When a conference is announced, a call goes out to potential speakers to submit a proposal for a talk. When following that call, you are confronted with a form that you have to fill out. Specifically, it asks you to submit a title for the talk and a short description of the content (commonly known as the "abstract"). Once submitted, you wait for the conference committee to accept your talk - and only then do you actually start working on it.
There's a flaw in this approach. Can you spot it?
