I am still saying it, and this is coming from someone who finds physics fascinating: medicine is way beyond anything engineering will ever accomplish. An aircraft is a mighty feat. We designed it. A space rocket? We designed it. Electromagnetic technology, bridges, computers, all of these are incredible feats, but ultimately things we designed and built from the ground up. Now think about medicine. Humans are opening up a body they did not design, navigating structures they did not create, knowing what to cut, what not to touch, what connects to what, where something needs to go and what carries it there and then putting the whole thing back together. That is, and will probably forever remain, mightier to me than anything we have ever achieved as engineers.
