And it's not so much the quantity (although comparing western with
eastern bloc country grocery stores is a nice juxtaposition), but the
price. Food prices have dropped markedly over the past century such that
significant government intervention is generally required to stabilize
food prices upwards against selling panics on an annual basis. Without
this intervention, prices would be even lower than they are, and there
would be even greater variety.

And even if they can't save it, they can frequently build robotic arms
that respond to nerve signals at ever greater levels of complexity.

Now they want to grow transplant organs for you on or in genetically
engineered farm animals. That photo of the mouse with the human ear
growing on its back was one of the coolest images I've seen. When this
becomes commonplace, expect human longevity to skyrocket. Today they
announced that they've successfully produced every type of human blood
cell from stem cells, leading to an end of the need for blood donation
drives and shortage caused deaths sometime in the next several years.

Ayup, which is why you want to look at overall economic data as well.
Rates of invention don't mean squat if they are not applied to human
lives. Economics measures this.
