Every time you take that amazingly small computing machine in your hand for granted.
Consider the wonderful program that is still providing us with amazing discoveries,
and
Marvel,
that that tiny phone in your hand has more computational power than the the entire mission control room that sent us to the moon did.

You can say that again, but only if one excludes the brains of the engineers and scientists in that room. Also, the computational brainpower of Isaac Newton had much to do with the success of that mission. But you're absolutely right to highlight the awesome journey from the slide rule to what's in our hands.
Yes the pace that technology advances is breathtaking, but the thing that is even more breathtaking is when you consider how throughout history people were able to achieve amazing things with earlier or even no technology.
