I think it would be hilarious if after all the EMH's advocacy in the end he wins and BOOM laws are made so no holograms ever hover near legal sentience again.
This was part of the plot of a novel i read years ago about a robot who became sentient and went through court to be declare "a person," the legal process takes two centuries. At some point the company that produced him changes the brains of their robots so no other robot could ever become self-aware.
The Positronic Man.
That was Isaac Asimov, Bicentennial Man. I loved that story.
