Roly Porter's hypnotic score is a constant companion to Dylan, with The Unheard composer finding poignancy and care in the protagonist's darkest moments. And as a sum of its parts, becomes an intense, sobering experience, one that aims to get us inside Dylan's deepest thoughts. Ultimately, pulls us under with Dylan, rattled and contorted into his high-stakes experiment without the ability to connect with him ourselves. Through MacKay's fearless performance, Wright's discombobulating style, and a timely theme, the film wrestles with existence and connection, balancing darkness and light, despair and hope. It's a haunting watch, but one with an all-important glimmer of hope.

IBM are not doing "cognitive computing" no matter how many times they say they are. I was chatting with an old friend recently and he reminded me of a conversation we had nearly 50 years ago. I tried to explain to him what I did for living and he was trying to understand why getting computers to understand was more complicated than key word analysis. I explained about concepts underlying sentences and explained that sentences used words but that people really didn't use words in their minds except to get to the underlying ideas and that computers were having a hard time with that. Fifty years later, key words are still dominating the thoughts of people who try to get computers to deal with language.
