This week we're joined by Lee Hickin, Microsoft Australia's National Technology Officer, who first of all tells us what he does and his background, and then talks about interesting artificial intelligence projects within public sector in Australia. He talks about the fish counting project in Darwin Harbour and the work being done in Kakadu National Park. What's clear is that Lee sees these successful projects as being a blend of technology merged with good professional judgement (something that makes sense in education too). We also talk about the responsible use of artificial intelligence, and what we're learning about good AI use - and why you can't just sit back and do nothing until the dust has settled. In fact, nearly half the time is spent discussing responsible AI, and frameworks for ensuring that we're using artificial intelligence well, in the service of users.
