... "I was proud as an engineer of what we were able to accomplish." Will the next century see the same amount of progress, or will technology yield diminishing returns to society's problems? "I don't know," said Lucky, but the list compiled by the National Academy of Engineering in 2003 of the 20 greatest engineering achievements of the 20th century offers some clues.
From page 14...
... These unanticipated inventions "had tremendous repercussions," said Lucky. "I haven't seen any of that yet this century." THE INVENTIONS OF THE FUTURE Today, if people on the street were asked to name the greatest engineering accomplishments of the 21st century, their most likely responses would be Google, Amazon, Twitter, and Facebook, said Lucky.
From page 15...
... However, his most confident prediction was that inventions will continue to occur that cannot be foreseen. "Those will be the miracles that none of us, unfortunately, will be able to see." The Changing Tools of Engineering When engineers of his generation came of age, said Lucky in response to a question, they did not have the computer power that young engineers have today.
