There was a time when products really had only two modes. Either on or off. But as peoples needs changed so did products and different settings were introduced. You can now dim your lights for example. But we are now again at the point where people want more. Or, less really. Less thought and more action on the part of technology.
I came across a new thermostat via Hacker News called Nest. Nest changes the way one thinks about what is expected from a thermostat. It is not about turning your a/c or heater on or off. It is not ever about setting up a schedule as to when to turn on and off. It is about getting to your optimal temperature with as little input from you as possible. It learns from you and adjusts accordingly.
Life is no longer binary. Software matters.
