The person would have to want to do it. How many criminals would volunteer to have thier personalities rewritten?
It gets even more interesting. How could you trust that they were really volunteering? When the alternative is Robot Jail, it would inherently be a coerced choice.
Every now and then I drop in on real-life courtrooms. A few days ago I saw a judge mention that the defendant had an outstanding warrant. The judge said she would quash the warrant but only on condition that the defendant sign herself in for inpatient treatment. The paperwork will show "voluntary commitment" but it was not voluntary. That may have been a humane diversion of a mentally ill person from the prison system but I'm not at ease with it.
I'd volunteer to have my personality re-written. and it's already well suited for being law abiding. Fighting that goddamned shyness every social interaction every day is a burden I could do without. But that would be outside of the pressures of the legal system.
How is (freely!) downloading a patch different from practicing things from self-help books?
Next digression: since apparently nobody in the public knows what Robot Jail is like, apparently nobody has written a Robot Jail memoir. There could be a market. The first person to write one could make money. May could use money. I sure get that she doesn't want to talk about it and I wouldn't nag her about writing if I knew her in "real life".
