I think the world is a better place if people are happier. Technology making bad and harmful things common and easy, is making the world a worse place. E.g. social media in the pocket. Technology causing more friction and annoyance is making the world a worse place, e.g. modern cars, modern computers. Technology causing people to lose their jobs is making the world a worse place (although it is arguable if general wealth and well-being in the west comes/came from robbing and enslaving other people, and cheap raw materials close to the surface). And so on, and so on.

edit: even new roads or bridges can cause worse traffic in general, see e.g. https://en.wikipedia.org/wiki/Braess's_paradox#Traffic
