A computer chip was inserted into Gavin's brain, rendering him a remote controlled operative of the CIA. He has given all the secret keys to the government and is helping to identify all bitcoin users who use Silk Road and who donate to wikileaks.
Also, it was recently revealed that Gavin is, in fact, an alien.
The chip also had the unforeseen side effect of splitting Gavin's consciousness into several distinct personalities, including, but probably not limited to, Phinnaeus, Atlas, and pirateat40. CIA technicians are hard at work writing the program for his ultimate mission: hunting down Satoshi and returning his/her brain for study. Little do they know, Satoshi's identity was discovered several months ago by a secretive cabal of Bitcoin worshipers and his/her brain has been divided into three equal portions and is in the custody of Nefario, Matthew, and Vladimir, to be reunited when the blockchain is in imminent danger, as foretold in the Great Prophecy of ENIAC in 1954.
You know, it's absurd conspiracy theories like this that give bitcoin a bad name. Everyone knows that the ENIAC "prophecy" was debunked long ago by the researchers at XEROX PARC. There is no shred of evidence to suggest that it should be taken seriously, and anyone who continues to cling to that failed machine's teachings needs to have the chip in their brain examined.
Okay, this thread is beginning to get way off-topic but let me just say that I'm very surprised that anyone would take the "research" coming out of XEROX PARC at face value. If there was nothing to ENIAC's warnings then why was Xerox systematically eliminating or brain-washing everyone who sought to publicize it? Thankfully, Jobs and Gates had the foresight to have it secretly encoded into their DNA so that it might at least be passed down through their progeny.
