To my children, Jonathan, Maya, Ron, and Tom - given the pace of the world we live in, in a few years when you are old enough to read this book, 5G is likely to become a thing of the past. Don't get discouraged by this in your aspirations to undertake any project you may think of, but do remember - time flies, so use it wisely. To my wife Tatyana, for the understanding that, despite not saying this as often as I should, I love you dearly, respect you deeply, and value everything that you do.
