not to be negative, but i think this is just Where Technology Is Now[1]
it's possible we'll see major breakthroughs again, but we've milked nanometer reductions past the point of diminishing returns
we need something that pushes battery density and thermal capacity in almost unparalleled bounds and without that i don't think wearables, much less anything AR, are ever going to Truly catch on
[1]: by which i mean i'm sure things will keep getting 1-5% better slowly for a while yet but i think the era of double digit gains at the same/lower power consumption is just Over
