This talk is super relevant to anybody writing a traditional monolithic web app. Eventually bugs creep in and you learn that your initial assumptions about transactions are basically all wrong. I really enjoyed that the talk extended to micro-services -- it gave a lot of insight into what you take for granted in your monolithic architecture when you start breaking things down. One tiny improvement I think could benefit the talk would be if the speaker commented about the usage of "SELECT FOR UPDATE" and maybe gap-locking.
