@David@setouchi.social Some general caveats, in case anyone wants to fight their inner old fart. 1) We're not really able to gauge "cognitive capability". What we do, is we make some measures that we hope somewhat correlate to "cognitive capbility", and we train these measures on pre-formed conclusions, i.e. we ask e.g. teachers to give their own hopefully not too biased opinion, and then we apply some statistical methods to make it all look "scientific". It remains some arbitrary measures. 2) Then what happens when we change how schools work? Or when society changes how families work? The measures are still measuring something that maybe kinda-sort correlate with "cognitive capability" some 20-30 years ago. But since families and schools changed, kids are learning different things, and the measures no longer align with that.Kids are still spending all their waking hours learning (it's unavoidable), but they are learning things that don't fall inside the measures we constructed for the previous generation. 3) Of course, none of that matters if kids are made to talk to Liar Liar Machines, because that really will suck the brains right out of their skulls, much like corporeal punishment and bullying.
