If I ruled the world: Cindy Gallop, founder of MakeLoveNotPorn

One law I would pass: A new legal definition of adult content. My startup MLNP fights a battle every day, because sex tech is refused everything other businesses can take for granted and it makes disrupting sex for the better extremely challenging.

Who I'd ennoble: All teachers, nurses, hospice workers and sex educators.

One thing I would ban: Gender bias, which holds back innovation and progress. Women challenge the status quo because we are never it.

Who I'd send to Siberia: The leaders of every bank. They wouldn't be allowed to return until they had cut out all fees and reminded themselves they work for the people whose money they bank, not the other way around.

Where I'd build my palace: I wouldn't. I'd take the budget and build as much comfortable shelter housing as possible for people who needed it anywhere in the world.

The book every child would have to read: A younger age-appropriate version of Al Vernacchio's For Goodness Sex for teens. In a world where children stumble upon porn on the internet as early as the age of six, learning about real world sex is critical for happy relationships and happy lives.
