Are You Saying That TaskRabbit and Yelp Should Embrace Blockchain?

Existing companies are late in embracing new technologies, maybe because they're afraid of cannibalizing the existing business right there. We all don't want to be the person who in 1992 said, Oh, why do we need internet? The main service works so well. So what I think is likely to happen is that some existing Ks will incorporate these technologies and then find beneficial applications. And yes, others will miss the vote.
