Taking the long view of the big technology trends that will shape our lives and the future of the planet in the decades ahead.

Technology moves fast - so where will it have taken us by 2050? How will it affect the way we live? And how far are we willing to let it go?

In Megatech, distinguished scientists, industry leaders, star academics and acclaimed science-fiction writers join journalists from The Economist to explore answers to these questions and more.

Twenty experts in the field, including Nobel prize-winner Frank Wilczek, Silicon Valley venture-capitalist Ann Winblad, philanthropist Melinda Gates and science-fiction author Alastair Reynolds identify the big ideas, fantastic inventions and potentially sinister trends that will shape our future. Join them to explore a brave new world of brain-computer interfaces, vat-grown cruelty-free meat, knitted cars and guided bullets.

The writers predict the vast changes that technology will bring to everything from food production to health care, energy output, manufacturing and the military balance. They also consider the impact on jobs, and how we can prepare for the opportunities, as well as the dangers, that await.

Thought-provoking, engaging and full of insight from the forefront of tech innovation, Megatech is essential reading for anyone who wants to understand tomorrow's world.
