Hmm? You think it's impossible for someone to go through 10-20 years worth of crypto patents, only to find that one of them contains the exact system architecture that was released as Bitcoin? I guess it's too much work for lazy boys like you :)
Another funny coincidence is the email that Satoshi chose to use in the whitepaper: [email protected]. Observe that `SatoshiN' can be interpreted as `Sat(4 chars)N', or equivalently: `Sat4N'! Meaning each time you send someone sats, you're actually sending them little satans. :)
There's no reason to theorize about anything. Maybe HBO should've hunted through all of the crypto-related US patents filed in the 10-15-20 years before Bitcoin was released. Happy hunting!
