Just an example of accelerating change.

There were rooms and devices in history that could be categorized as planetariums dating back to the 13th century, but the first true planetarium was created in Munich in 1920.  [ref. linky] [wikipedia]

That planetarium used a metal dome with holes poked in it to project the lights onto a domed ceiling.  This technology remained largely unchanged for 60 years.

Since then we have seen rapid change.  With computer processing  power increasing continuously it is now possible to provide dynamic content up onto the dome.  I went to a local planetarium last year and the experience was more like a trip through space than a lecture from an instructor.  It was remarkable.

But it doesn't stop there.

We now have sophisticated programs available to everyone for free that exceed the capabilities of ANY planetarium that was built before the year 2000.  Stellarium [linky] is only the most sophisticated example.

The power of a full planetarium placed in your hands for free.

Accelerating Change:

This is only one trivial example of accelerating change in our lives.  We have the capabilities at our fingertips that only large institutions have had in the past.  And even those institutions, whether business or government, have only had THOSE capabilities for a hundred years or so, before that essentially nobody could do these things.

And we take it all for granted.

We shouldn't.

We live in an age of miracles.  It is not an age of once in a blue moon someone gets healed by some mysterious means or someone walks on water or something trivial like that.  It is an age where the miracles are so common and ubiquitous that they have become mundane.
