What couldn't it do? Eventually there will be programs, not games. You'll make the games yourself with minimal prompting. Want an Abe Lincoln hack and slash with no escort missions? Sure, the first one won't be what you want, but the second will be closer. User generated content isn't going away, but neither is the rise of personal gameplay customization. Think sliders for QTE frequency, stealth sensitivity, amount of lore, number of endings, scale of locations... We will soon be able to play exactly the game we want.
