Your argument is not rational, you cannot just throw false statements without even proposing proof of what you aim to claim.
> I don't think they started developing the iPhone in 2007
Development of what was to become the iPhone began in 2004. Just 3 years before being publicly available, which is similar to the two years of development for BTC.
