How come they have not developed a digital grading system for all coins, just run them through a scanner and all the imperfections would be caught and coin would be graded. Human grading is obsolete and errors are made.

...because we buy into subjectivity.

Because "eye appeal" is a significant component of market grading, and it is impossible for a computer to assess and accurately judge eye appeal. 

It would take money, research, technology, and work, but a program could be devised which measured the luster, strike, and contact marks of the coin. That's the science of it. But the eye appeal is art - and no computer can accurately judge that. That's why there is an Art and Science of Grading Coins - and robots aren't there yet.

Perhaps one day A.I. will decide to collect widgets and the N.P. (Numismatics Program) won't allow for error, so the Nanites stay busy on the surface of the widget sweeping and plowing molecules about that somehow got misplaced in the inert argon matrix.

They did, 36 years ago. (well not for all coins, at the time it could only do Morgans and possibly Saint Gaudens double eagles)  It could grade, it was consistent, and it could recognize coins that were resubmitted to try and get an upgrade.  And it was scrapped less than six months after it was introduced.  Too much disagreement by the coins owners with the grades assigned, and since the system recognized resubmissions, no chance of getting an upgrade.
