In his Long Now Talk, John Markoff was joined in conversation with Long Now's Co-founder Stewart Brand and Executive Director Alexander Rose around Markoff's new biography of Brand.

Journalist John Markoff writes about technology, society and the key figures who shaped Silicon Valley and the personal computer revolution. Along the way, his stories and reporting intersected with Stewart Brand's paths numerous times and in surprising ways.

And now Markoff has distilled Brand's formative rise from the Merry Pranksters and the Whole Earth Catalog, to the marriage of environmental consciousness and hacker capitalism into his newest book, Whole Earth: The Many Lives of Stewart Brand.
