Sergey Brin says Google 'failed to be on the bleeding edge' of blockchain

Blockchain has triggered in the past several years, not only Google but many other giants missed the chance to invest and develop blockchain to get the highest profits, to be leading over the globe. However, this may be quite late, but I think blockchain's still worthy to invest for more profits. It seems to be risky but if they can do more research and learn how to manage that, they will further developing blockchain technology.
