Today mammography requires an expensive, large, stationary machine that takes a crude, two-dimensional picture. But imagine a 'bra' that has tiny X-r… - Peter Diamandis

For Page, like Musk and Branson and Bezos, that answer always sits at the intersection of long-term thinking and customer-centric thinking:

Marc Goodman is a cyber crime specialist with an impressive résumé. He has worked with the Los Angeles Police Department, Interpol, NATO, and the State Department. He is the chief cyber criminologist at the Cybercrime Research Institute, founder of the Future Crime Institute, and now head of the policy, law, and ethics track at SU. When breaking down this threat, Goodman sees four main categories of concern. The first issue is personal. "In many nations," he says, "humanity is fully dependent on the Internet. Attacks against banks could destroy all records. Someone's life savings could vanish in an instant. Hacking into hospitals could cost hundreds of lives if blood types were changed. And there are already 60,000 implantable medical devices connected to the Internet. As the integration of biology and information technology proceeds, pacemakers, cochlear implants, diabetic pumps, and so on, will all become the target of cyber attacks." Equally alarming are threats against physical infrastructures that are now hooked up to the net and vulnerable to hackers (as was recently demonstrated with Iran's Stuxnet incident), among them bridges, tunnels, air traffic control, and energy pipelines. We are heavily dependent on these systems, but Goodman feels that the technology being employed to manage them is no longer up to date, and the entire network is riddled with security threats. Robots are the next issue. In the not-too-distant future, these machines will be both commonplace and connected to the Internet. They will have superior strength and speed and may even be armed (as is the case with today's military robots). But their Internet connection makes them vulnerable to attack, and very few security procedures have been implemented to prevent such incidents. Goodman's last area of concern is that technology is constantly coming between us and reality. "We believe what the computer tells us," says Goodman. "We read our email through computer screens; we speak to friends

Greenblatt is not alone in this assertion. Many believe water is an issue of money and will be best solved locally, and without the aid of techie gizmos. It’s an opinion based on hindsight. The last century saw governments dithering while they searched for a high-tech, silver-bullet solution. Millions died in the interim, and the world is full of gadgets either unsuitable for the ruggedness of their deployment area or impossible to maintain because supply chains did not extend far enough.
