The IAI's world leading festival of ideas and music HowTheLightGetsIn Hay 2025 returns this autumn. Instead of our online event, we're welcoming the globe's greatest thinkers to the banks of the river Wye.  In the first of the summer sunshine, they'll lock horns over everything from dangers of democracy and the future of peace in our world, to the riddle of the universe and the query of AI's creativity.
