So unfortunate Satoshi should have been the one to answer this question.
Do you still call him unfortunate after all the progress and success and bitcoin never die, you're still in your old mentality and operating on it thinking nothing is wrong.
I guess you misunderstood the whole situation. Based on what I understood, he meant it's very unfortunate that Satoshi can't be here to answer the question himself, which I see as the OP referring to the situation being unfortunate and not directly meaning that Satoshi is unfortunate; his creation is a success, and no one unless those hypocrites who are looking for every opportunity to criticise bitcoin can use such a word against its creator.
Actually Satoshi can't answer this question, but I will stand by saying that many his did has change the narrative of life as as much as human in dealing with currency is concerned and can be regarded as unfortunate situation as OP used though the unfortunate I don't really know it perspective is referring by the way. He has move to the other side entails allot the state is relative and can be interpreted based on how you view it, until he come to tell us what it means. Pointing with others senairo, like I learnt in my school days Micheal faraday did an incredible things to light that the world enjoy today for humanity despite he did not enjoyed it due to some experiment that leads to his departure as history tells but can't been see as unfortunate because it's sacrifice stand to usher humanity good living. The other side to Satoshi may be more discovery as nothing has state about his been for now.
