The Wall Street Journal’s podcast “The Future of Everything” is a useful, business-focused look at technology and innovation, presenting new technologies and ideas in a steady weekly feed. The festival packs all that into three days of workshops and presentations, and since it’s themed around a podcast, you can “try before you buy” as presentations from last year’s festival are loaded onto its feed. Especially for non-tech businesses that need to develop more of a tech focus, this will offer plenty to mull over.
