The circular slide rule reminds me that in my long-ago engineering degree I used (though now, not how) a “steam chart”, officially an entropy/enthalpy diagram with lots of curves. ISTR that they were for different pressures. Some time later, involved in power station operation, I found that actual practical steam pressures were way beyond the range of the chart.
The article on AI is very interesting indeed.
They mention difficulty training it to recognise aggressive behaviour and I can’t help but wonder if the reason was that it picked up an inappropriate racial bias and thus had to be de-trained.
