Measurement is, of course, a key issue, but it's less clear than you think that these changes represent forward progress.

Device convergence is pretty handy, and the shift towards spacial minimalism suits me nicely.

Is having less time in shared physical space, fewer "third places" really good? Do virtual replacements -- and their tendency toward sorted-ness -- really replace them effectively?

But most of all, a narrower demand profile leads to people who are left out of the labor market (and an even larger number of people who may be included but are poorly rewarded).

Make sure any alternatie measure you suggest keeps an eye on these issues.
