Given Paul D's trackrecord of combining 1. smugness 2. being wrong, and 3. a complete unwillingness to engage (beyond mentioning his degree)... I should have stuck with my original comment - i.e. **** off.
For anyone else who is interested in how to measure inflation under a rapidly changing technology. Have a look at the below.

I see another conclusion from this chart: statisticians cannot measure the impact of technological deflation. According to the hard-working statisticians of the Bureau of Labor Statistics, the price of phones dropped by 62% between 2004 and 2014. Where did this number come from?
In 2004, the cutting-edge of mobile techology was the Motorola Razor V3, which sold for $500 with a two-year contract. Today, Verizon offers the iPhone 7+ for $650 with a two-year contract. So the 62% price drop recorded by the BLS is really the product of a 30% nominal price increase and a 71% “hedonic adjustement”. According to the BLS website, “hedonic quality adjustment is one of the techniques the CPI uses to account for changing product quality within some CPI item samples. Hedonic quality adjustment refers to a method of adjusting prices whenever the characteristics of the products included in the CPI change due to innovation or the introduction of completely new products […] The CPI obtains the value estimates used to adjust prices through the statistical technique known as regression analysis. Hedonic regression models are estimated to determine the value of the utility derived from each of the characteristics that jointly constitute an item.”
How the BLS’s fine statisticians came up with the 71% adjustment is a mistery. How can one put a value on the fact that today’s phones have better cameras than professional equipment 10 years ago? That they have replaced books, newspapers, maps, video game consols, encyplopedias, torches, compasses, laptops, desktops, friends, dating services, camcorders, travel agents, translators, movie theaters, realtors, TVs, bank branches, and retail stores?
Yet, all these adjustments eventually feed into Consumer Price Index All Urban Consumer (CPI-U) and into the Fed-beloved Core Personal Consumption Expenditure (Core PCE), which ultimately drive monetary policy. The price of time, the cost of credit, and the size and composition of the Federal Reserve’s balance sheet are eventually derived from the hedonic adjustments of obscure statisticians in a neo-classical building on 2 Massachusetts Avenue.
Next up we have the Chief Investment officer of blackrock talking in simple terms about the same issue.

"We're going through an incredibly historic pinpoint in time where you've done this amazing downward pressure on inflation coming through technology," Rieder said Tuesday on CNBC's "Trading Nation." "It's a very, very different dynamic than anything we've ever seen before."
The most direct illustration of this is the fall in prices of computing power and data storage.
"An iPhone in 1991 storage and computing cost dollars would be worth $1.44 million per phone. An iPhone today costs a minuscule portion of that," he said. "That gives you some sense for this incredible inflationary impact on so many things that are now done via mobile or done through automation."
With the chart
So theres two major points here.
1. That different segments in the economy are changing prices in very different ways. A single number doesn't capture that.
2. There are significant difficulties in measuring price changes when quality changes so dramatically.
Against all of this, we have monetary policy that "should" be increasing inflation, but all we are seeing is a dramatic rise in asset prices.
