Years back, I had a manager whose hand-written missives were generally difficult to make out.
Then the firm rolled out a thing called a "Tonto", known in the real world as an "OPD", which was a dressed-up Sinclair QL, with the full suite of office programs for inter-office communication. That was when we found out he couldn't spell, either.
It will be interesting, probably in the near future, when one of these modern semi-literates issues an instruction whose misinterpretation that takes him to court. The world is becoming increasingly litiginous, and courts tend to go with physical, in this case paper, evidence.
