Here's an idea that I think has a good chance of happening irl (at least above 1%, lol).

In about 4-5 decades from now we reach total mastery of genetics and brain scanning, allowing us to easily craft dispensible clones of real people or just genetically engineered specimens that are perfect in some way or another. This is coupled with the advent of a new brain scanning technique that uses a sort of implant that reads the brain activity of a person for a few months before it's extracted. Afterwards, a sufficiently powerful AI algorithm is used to analyze that recorded data and make a copy of that person's...personality. This is coupled with the human clones to basically create any sort of human one could imagine, in a matter of weeks. Having so much control over the production of such a human would probably also mean being able to suppress his/her primal instincts such as the will to live.

You probably see where this is going. You also probably see that there would be a lot of people debating over the ethics and arriving at the conclusion that it would probably immoral to snuff these manufactured humans... but I believe that a country like North Korea (if it even exists in a few decades, lol) could use this technology to revitalize it's economy (first by slavery)... and also provide the rest of the world with the only place to go and legally snuff 'people'. I think it would be feasible for them to open a dolcett style park there, if this technologies would indeed be developed.

Aah...but then again, this might be just another brainfart. By that time it would probably be way more efficient to create virtual reality programs with 'full dive' experiences that could provide the same snuff entertainment.
What's it sound like? I for one will probably write at least a sketch or two in this possible future.
