As long as the generic topic is being commented on...

The difference between a "slow" adoption rate and an adoption rate of 
essentially zero is fundamental.    So yes, a pure single number of 
years can be misleading and needs some sense of whether the is any 
progress at all.

There also needs to be some care about marking the start of the clock, 
given that some technologies have multiple components needed before they 
are worth adopting, and an initial, incomplete set might be published 
before a sufficient set is available.
