Let us know by answering our poll. +![video editing dashboard][1] + +At [DevFest DC][2] in June, [Sara Robinson][3], developer advocate at Google Cloud, gave the most seamless live demo I've ever witnessed. + +Sara live-coded a machine model from scratch using TensorFlow and Keras. Then she trained the model live, deployed it to Google's Cloud AI platform, and used the deployed model to make predictions. + +With the exception of perhaps one small hiccup, the whole thing went smoothly, and I learned a lot as an audience member. + +At that evening's reception, I congratulated Sara on the live demo's success and told her I've never seen a live demo go so well. It turns out that this subject was already on her mind; Sara asked this question on Twitter less than two hours before her live demo: + +> Do you prefer watching a live demo where everything works perfectly or one that breaks and the presenter has to de-bug? +> +> — Sara Robinson (@SRobTweets) [June 14, 2019][4] + +Contrary to my preference for flawless demos, two-thirds of Sara's followers prefer to watch de-bugging. The replies to her poll were equally enlightening: + +> I prefer ones that break once or twice, just so you know it's real. "Break" can be something small like a typo or skipping a step. +> +> — Seth Vargo (@sethvargo) [June 14, 2019][5] + +> Broken demos which are fixed in real time seem to get a better reaction from the audience. This was our experience with the All-Demo Super Session at NEXT SF. Audible gasps followed by applause from the audience when the broken demo was fixed in real-time 🤓 +> +> — Jamie Kinney (@jamiekinney) [June 14, 2019][6] + +This made me reconsider my preference for perfection. When I attend live demos at events, I'm looking for tools that I'm unfamiliar with. I want to learn the basics of those tools, then see real-world applications. I don't expect magic, but I do want to see how the tools intend to work so I can gain and retain some knowledge. + +I've gone to several live demos that break. In my experience, this has caught most presenters off-guard; they seemed unfamiliar with the bugs at hand and, in one case, the error derailed the rest of the presentation. In short, it was like this: + +> Hmm, at least when the live demo fails you know it's not a video 😁 +> But I don't like when the presenter start to struggle, when everything becomes silent, it becomes so awkward (especially when I'm the one presenting) +> +> — Sylvain Nouts Ⓥ (@SylvainNouts) [June 14, 2019][7] + +Reading the replies to Sara's thread made me wonder what I'm really after when attending live demos. Is "perfection" what I seek? Or is it presenters who are more skilled at de-bugging in real-time? Upon reflection, I suspect that it's the latter. + +After all, "perfect" code is a lofty (if impossible) concept. Mistakes will happen, and I don't expect them not to. But I _do_ expect conference presenters to know their tools well enough that when things go sideways during live demos, they won't get so flustered that they can't keep going. + +Overall, this reply to Sara resonates with me the most. I attend live demos as a new coder with the goal to learn, and those that veer too far off-course aren't as effective for me: + +> I don’t necessarily prefer a broken demo, but I do think they show a more realistic view. +> That said, when you are newer to coding if the error takes things too far off the rails it can make it challenging to understand the original concept. +> +> — April Bowler (@A_Bowler2) [June 14, 2019][8] + +I don't expect everyone to attend live demos with the same goals and perspective as me. That's why we want to learn what the open source community thinks. + +_Do you prefer for live demos to be perfect? Or do you gain more from watching presenters de-bug in real-time? Do you attend live demos primarily to learn or for other reasons?
