Podcast: Howes on Silicon Valley muscle

Detroit News Columnist Daniel Howes and Michigan Radio are partners in weekly essays examining what's hot in Michigan business and politics -- and what it all means. This week, Howes says the biggest threat to Detroit and its hometown auto industry aren’t foreign rivals with names like Toyota, Honda and Volkswagen. It’s the tech revolution in the global auto space, and the moves by such Silicon Valley heavyweights as Apple, Tesla and Alphabet’s Waymo to grab large slices of an emerging multi-trillion-dollar business.
