“Years and Years” showrunner on when tech’s great and grim

Host Molly Wood speaks with Russell T. Davies about his BBC-HBO show “Years and Years.” Davies says that the family featured in the saga are forwarded 15 years into time and they experience every technological and humanistic evolution possible, like a character coming out as trans — not transgender, but transhuman (some robot parts in her). They also talk about the technology featured in the series.
