It really depends.  Some seminal live coding has introduced for me new programming techniques in a really impactful way.  I needed the programmer to talk through and introduce the techniques as they worked slowly because I needed time for what he was saying to pass the BS filter and otherwise ring positive bells in my head.<p>The most recent instance of this for me was a talk on TDD that featured testing, of all things, CSS!  My eyes were opened and I am now trying to test-drive my CSS with the tools&#x2F;techniques described.<p><a href="https:&#x2F;&#x2F;vimeo.com&#x2F;144642399" rel="nofollow">https:&#x2F;&#x2F;vimeo.com&#x2F;144642399</a><p>There are some funny moments at the beginning and a good agile intro overall, but the CSS TDD part starts at around 21:00 if you are interested in that.
