It's a wrap! What was your personal highlight?

It's a wrap! Berlin Buzzwords 2021 is over. We have had four amazing days full of learning, gathering new experiences, and meeting new people! In a fully virtual environment we had a great selection of talks, workshops, debates and discussions by amazing speakers from all over the world. Some were first time speakers at #bbuzz, others were popular speakers returning to share some new ideas and insights.
