AI may allow for advanced medical procedures using its ability to consolidate/review vast amounts of data and use, say nanobots, to repair/reconnect nerve endings, muscle, and other flesh. This could allow people to live longer lives It could also allow people with severe trauma to be healed and live long lives. And it could allow bodily transmogrification that we can only imagine today.
People are competitive and the masses need circuses so they say. With more leisure they may engage in more sports. The sports we have today may become boring and something more extreme come to be. Think about the Roman arena or jousting or dueling or Old West style quick draw gun fights, all to the death. Except, think about the first paragraph above, so maybe not to the death. The loser gets fixed up to fight again. Think about the last sentence of the paragraph above…somebody gets to compete transmogrified to a lion or Dire Wolf.
