Brave New World
Christopher Exley poses some important questions . One thing I would point out here is how slippery are such terms as “disinformation” and “misinformation”, shifting the issue of whether something is true or not (which is complex) to whether it is politically convenient. An algorithm cannot possibly sort out truth but it may be excellent at suppressing ‘the wrong sort of information’ - which is something quite different, and politically retrograde. Readers can perhaps understand the crudity of this process from this recent Wall Street Journal video , though the presentation is glossy enough.
As Exley points out such a high-handed strategy is the last way to earn trust - if that was ever the purpose - and could frankly cause all sorts of social and political turmoil (the USA and Italy anyone?).
