Unfortunately, the law generally does not evolve as quickly as technology. The 1967 phone booth case was the first time telephone conversations were recognized as constitutionally protected from unreasonable searches—nearly one hundred years after the telephone was invented. The Internet and cloud computing have taken a fraction of that time to reach wide market penetration, and show little sign of slowing down. But since Moore's Law does not apply to legal innovation, the disparities between technology and the law are likely to become even greater.
