1/ What do jets and dishwashers have in common?

2/ both have gotten more efficient in the last half century. They use less than energy and make less noise.

3/ but the problem is in both cases we’ve focused on the efficiency of the machine, not the efficiency of the *human*

4/ so washing your dishes takes as much effort as it did in the 1960s. And your flights are even longer and less convenient

5/ we desperately need a human-centric view of innovation, which views our time and *human* energy as the limited resource—not water or electricity or jet fuel

6/ instead of asking ourselves how we can conserve, we should challenge ourselves to create abundance

7/ as humans, we need to add to our time (longevity) and increase our productivity and happiness per unit time (many factors)

8/ and therefore what we need from our technology, fundamentally, is the ability to do more with less time and (human) energy

9/ I’ve found that if you take this view—of *human* energy as the limiting reagent in the chemistry of progress, you end up with a very different view of what efforts are most important to pursue, and how best to pursue them
