If this guy is shown to be fake - and you know, you can't prove a negative, but if it seams beyond reasonable doubt he is not satoshi (and this post is fairly persuasive
http://jere.in/dr-wrong-and-the-art-of-digital-misdirection) then that is so sad.
An important debate that has been going on since Satoshi's first announcement really with the first post stating it won't scale, might have now been decided solely by some conman (if it is shown so). The agreement was breached, almost everyone attended the Consensus conference. It was the biggest event in Bitcoin's history by the level of speakers etc, so much exciting stuff was likely to come from it, and did come from it, but we instead were all talking about this guy.
Whatever, miner's decision I guess. Bitcoin will still work, it's not like it will break down. Maybe it will walk now, instead of run, but whatever. The picture is far bigger now. Blockchain tech is super hot, Ethereum is finding some corporate acceptance, then there is hyperledger and whatever Corda may do in regards to banks as well as
ChinaLedger which this guy overshadowed.
A lot of exciting things are going on, with bitcoin now just one of potential winners of what I like to call the greatest race, certainly of the decade, but maybe century.
