I was thinking about 'shearing layers' and 'pace layering' for this Lift talk - that might be how we get at the ends of the 'innovation' scale - thinking about how deep into the layers we're digging.
Then, with his usual immaculate timing, my old boss posted some more (related) Stewart Brand wisdom:
"The fast moving trends get most of the attention. The slow moving trends have most of the power."
There's lots in that. The flashy version of innovation gets you attention, gets you on the front cover of Wired. Dealing with infrastructure, governance and culture gets you deep, lasting difference.
Both are useful.
