It might have been my expectations, but during this talk I was hoping to learn about actual production use cases where the developers faced a particular unexpected or compounded issue. However, during the talks I learned the system was still being developed and is yet to go live. As I was working on a live event sourcing system at the time, this didn't increase my confidence that the content would be relevant to me.
Overall, the speakers had the right mix of relevance and entertainment, to keep the listeners engaged. The switches between the speakers felt quite forced, though.
