If you want to know why artificial intelligence is like teenage sex, this is the post to read. After opening with that arresting comparison, the article goes on to make a couple of simple but important points. Most real world activities are not games with pre-defined rules and spaces. And for businesses – and arguably still more so for governments – it is critically important to be able to explain and account for decisions and outcomes. More pragmatically, it also argues that competitive advantage in the deployment of AI goes to those who can integrate many sets of disparate data to form a coherent set to which AI can be applied. Most companies – and, again, perhaps even more so most governments – are not very good at that. That might be the biggest challenge of all.
