There's something called a Conchoidal fracture, https://en.wikipedia.org/wiki/Conchoidal_fracture ... the presence of which is technically diagnostic of material that's been artificially manipulated.
As per your sentiment , we should all be doing whatever we can to restore dignity to those that need it.If you ask that of Kamen , you should certainly ask for it from yourself.
You are presumably reading this on a computer you own , and drive to work on a car you own. You can increase the dignity of a number of people by selling both and donating the proceeds to a worthwhile charity. ( I can think of few things more dignified , than say , for a starving kid in India to be able to go to bed with a full stomach for one night). And charities like giveindia.org make this very possible ...
And yet you haven't ... You might argue that there is no way you could do without either.
How is Kamen's "indulgence" in building a Segway any different? The starving people would be annoyed with you too,as you indulge yourself with luxuries like cars and computers , when they have to debase themselves just to feed themselves and their families.
(No offence intended. :) When I say "you" , I mean us )
