People will care when we reach the point where we can tell them that the US dollar is being printed at a faster rate than the bitcoin is being mined.

That's been true since the day bitcoin started.
The largest ever increase in bitcoin in a
year was less than 3
million bitcoin.
In the
month between December 2015 and January 2016 the US dollar supply increased by more than 80
billion dollars.
Yeah, I think you have to compare them in like units, or do it on a percentage basis. In other words, those 3 million bitcoins are currently worth $416 each, so you can then extrapolate in USD terms what the effective rate has been over a given time period, or just compare the dollar for dollar amount (which, of course, in that time period, is still less than the 80 billion dollars in current dollar terms).
