This video is exceptional on a number of levels. Peter Dahmen, the engineer interviewed, does amazing work. And yet had he been rich enough to not have to ride public transportation he might have missed entirely an opportunity to excel. Sometimes embracing the challenges life throws at us can take is in amazing directions we might never have found otherwise. His comments about having to try and fail numerous times to get the beautiful, finished products you see is also foundational.
And, if nothing else, the works he creates lend credence to the idea that any technology, if sufficiently advanced, is indistinguishable from magic. These look like magic to me, not a lot of engineering and hard work.
