I know the coffee's ready because the light in the Quartz kitchen is purple, not pink. The light knows the coffee is ready is because there are sensors--heat and pressure--taped to the coffee maker. This is the internet of things. It will save us all from economic ruin.
Or at least that's what a new estimate from innovation guru Michael Mandel says. He figures (pdf) that the "internet of things"--the increasing number of machines equipped with internet-connected sensors--will expand the US economy by $600 billion and $1.4 trillion in 2025, roughly the equivalent of boosting GDP by 2% to 5% over the intervening time period. That could be the difference between so-so growth to the kind of stable growth that drives down debt and unemployment.
More broadly, the argument he's making is a reply to economists like Robert Gordon and Tyler Cowen who fear that the big gains in productivity that supported an expanding middle class and the modern welfare state won't be replicated anytime soon. This has major social repercussions--namely a scenario known as the great stagnation. The internet, for all the ways its changed our lives, has offered its gains largely in the form of consumer surplus--free stuff on the internet you used to pay for, in short--that is great and important but not necessarily money in your pocket.
Today's internet of things is limited to consumer surplus, like Quartz's coffee pot monitor or our weather bulb.
Another hope Mandel holds out for the technology is to make on-the-job-training easier by making machines more responsive to their users.
