Ask HN: What current new projects take advantage of future accelerating change?

Ray Kurzweil has said that he succeeded in his startups by tracing where technology would be 5 years into the future (the approximate time for a new project) and building his systems to that spec.<p>For example, in his pioneering OCR (including readers for the blind) and voice recognition, he relied on hardware that had not yet become economical, writing software that wouldn't effectively work on the usual hardware available at the beginning of the project.<p>It has been said that Facebook succeeded where Six Apart and Friendster did not because only in the mid/late 2000's did economical server hardware become strong enough to support so many users.<p>What specific startup ideas can we talk about in late 2012 that will succeed because they will be the first to leverage the greater power of infrastructure that is NOT available today?
