> The elephant in the room here is that within the mathematics, physics and computer science communities there are a significant proportion of people who are “on the spectrum”. They lack empathy and are usually appalling teachers. If you are a student who has not “clicked” with the subject these people will never get you to a point where you understand it.

Says the author without providing any piece of data or source of information. In particular

- where is the data that shows there's a significant portion of peoples on the spectrum in these fields?

- where's the data or source of information that proves that people on the spectrum are less empathetic?

- where's the data or source of information that proves that people on the spectrum are appaling teachers?

You can't launch such a statement without providing any source of information or data. Please, do good science, specially when talking about a vulnerable group.
