S Club 7, in some ways, was a continuation of some of the things I'd have liked to have done with the Spice Girls. It was also a shift in tone. S Club was this equality of boys and girls, very positive, very uplifting, didn't have the edge of the Spice Girls. I didn't want to repeat it.

My business is creating fame and celebrity, and I'm one of the best in the world. I know it to the finest detail. I reflect what's out there, and if there's a demand for something, I recognise it. I don't think I'm crass. I stand by everything I do.

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

My view of social media is that it is a set of tools, not a religion.

Whether it is through stock-market trading or the sale of hotel rooms, the Internet has a way of bringing deflationary forces to all businesses that were hitherto inefficient and involved many middlemen.

The early idealists and companies and governments have all assumed that the Internet will bring freedom. Yet China proves that this is not the case.
