I am very happy to get back to the original topic of the thread, ie child genius. I was criticising Mr Williams for throwing us off course, for what is by no means the first occasion (and I believe it will not be the last, unless he is moderated) with his obsession with AM's brief clip in a TV programme shown some six or more years ago.
And I don't care that he doesn't know whether I am a chess player! (perhaps at this precise moment only the ECF can answer that, in any case
There is no agreement as to whether child prodigies (of the Adams/Short/McShane class) should stay at school. Even each of those three went separate ways - Adams left school in all but name at 16, Short made a more serious attempt at A-levels, I think, and Luke went to Oxford. However I think the pace of life at the top in the chess world partly answers it for us. You will very likely be over 2600 by the age of 16 already if you are destined for a good career in playing
chess (though maybe we can substitute ages up to 19-20 in cases where the young player came from a country with few playing opportunities and perhaps a low starting rating).
More generally, I can think of many more highly talented people who regret ending up as chess "professionals" than regret seriously studying some good academic subject, despite that the latter is far more normally undertaken. This is one distinction from most other genius sportsmen. I believe that most chess players can trasfer their intellectual skills, if only they are willing to do so.
