“It’s only the Internet of Things while it doesn’t work.

  • As soon as it works, it’s a thermostat.”

WHY NOW?

  • WHAT HAS CHANGED?
slide-11
SLIDE 11

Software

  • Open source
  • Ease of use


e.g. BBB IDE

  • Big Data platforms,

tools, technologies Hardware

  • Open source
  • Innovation in cost /

power usage / sophistication

  • Maker movement
  • 3D printing
  • Fabrication services
  • Easy-to-use building

blocks (e.g. Arduino) Culture

  • Drive for greater

effjciency / knowledge / safety

  • Making decisions on

evidence

The confluence enables new classes of applications to be built

WHY DOES IT MATTER?

–Jefg Hammerbacher, Facebook’s first data scientist

“The best minds of my generation are thinking about how to make people click ads.

  • That sucks.”

From a technology perspective, good web software delivery is a solved problem

  • IoT has lots of unsolved, worthwhile problems that are

very challenging

Resilience is important

  • Prototyping with a 3D printer is liberating
  • Integrating the digital and physical worlds is a whole new

ball game
