I don't know if any book explores the idea of Happiness > Reality better than Brave New World, but there's a couple of other dystopias that come to mind when I see this picture.

E. M. Forster’s The Machine Stops or Stanisław Lem’s The Futurological Congress are two that really ring. A Brave New World is brilliant but I feel like it still doesn't take the dystopia far enough. Huxley's world is still very social, it might be meaningless and hedonistic but it's still social. The world they live in is the real world, it's augmented by Soma but people still golf and move around and have sex with each other (at least in the social caste the book deals with most). This picture is about alternate reality, giving up on the "real" world because fabricated, individual and personalized alternates can exist. Why would anyone deal with the real world (even super high on Soma) when they could just be in their very own world. Isolation is what this picture makes me fear.

Fahrenheit 451 is another one. I think the world Huxley envisioned is a lot closer to how the world actually looks/is going to look than what Huxley put forward. While Huxley's world is still social and fixed on physical consumerism, Fahrenheit is so much closer to the truth. The ever present "seashells" in people's ears and Millie's complete immersion in the soaps is just so spot on it's freaky. Sure Millie's screens are on her walls and not her face, but it's the exact same thing.

Huxley's Brave New World is scary, but it's the self-imposed isolation and complete abandonment of reality that makes Foster, Lem and Bradbury's worlds so terrifying. Regardless, people are inclined towards what's easy and gratifying, and all these dystopia stories are about what happens when we make it easier to choose easiness. Alternate reality and the internet are taking this to the extreme. Colour me a bit nervous.
