On 17 April 2020 I published a piece entitled “The COVID-19 Spread in Australia” on behalf of its author, my friend John Edwards. Since then we’ve kept in touch and discussed this matter a good deal, most especially how this virus is affecting the world as a whole, and certain nations in particular. We’ve watched with a good deal of alarm as the US administration has dealt with the crisis and how, in spite of the confusing and contradictory output of the Whitehouse, this resilient and resourceful nation has somehow been effective in coordinating and making…

Artificial Intelligence (AI) has hit some important benchmarks. In some fields it’s not just able to eclipse your average human, but to beat world masters in such pursuits as chess and go. This appears to have happened overnight, but in reality comes on top of fifty years of alternating optimism and despair. For example, I recall opinions from the early 1980s discouraging careers in computer programming, based on the view that computers would very soon be programming themselves. How’s that working out? In reality, compelling general AI is still a ways off, but there are plenty of specific tasks that…
