Being in the crowd during this talk was seriously like being at a rock concert.<p>Beazley was &#x27;playing&#x27; the keyboard like an instrument.  Every square inch of floor space had someone sitting or standing.  The crowd was incredibly invested - nary an eye nor ear wavered.  Even Guido looked on with a hawk eye.<p>I was in a small circle on the floor of people who had just smoked some amazing herb before the talk.  I was hanging on his every word and every expression.  I&#x27;ve rarely felt so engaged by a conference talk.  I&#x27;ll never forget this one.<p>He received a <i>raucous</i> standing ovation that is not evident from the conference video.<p>I asked a question at the end, and I was so giddy I had trouble getting it out.  :-)<p>As a core contributor to an async framework, I felt that this talk gave me a lot more enthusiasm and confidence about my work which has lasted to this day.  I think about it often.  Definitely a track for the PyCon greatest hits album.
