Serial conference organiser Alexy Khrabrov: what are his learnings?

I was at the Rethink Trust conference which revolves around blockchain engineering and I spoke to Dr. Alexy Khrabrov. Alexy is a serial conference organiser and he organises a lot of conferences (in the Bay Area) in fintech, AI, self driving cars, big data and blockchain from an engineering perspective. Why is it important to have that engineering perspective? He reflects on his inspiration, his worries, his first European conference and the responsibility of coders. How does he view the future of (de)centralization? What are his views on the current status of self driving cars? Alexy organises conferences in different fields of subjects and he explains the importance of this.
