Losing the art of handwriting

I know much has been written about the demise of beautiful handwriting, especially as penmanship is no longer taught in schools.  But I also think about it every time I pay with a credit card and scribble a line with a thick blunt stylus that can barely be held comfortably, while standing, balancing a wallet and trying to write with the "pen" that is still attached to the device's pad by a too short string. What does a signature even mean anymore? Does this meaningless scribbled line even hold any legal weight? When I recently dropped in to the Wells Fargo Museum in Old Sacramento, and saw this run-of-the-mill telegraph paperwork from 1874, it was so apparent that we have lost a real art: one that everyone did effortlessly.
