Excellent article. I think HRs political correctness was misguided.
There are many aspies in IT, esp. programming, as you mentioned, it is generally a safer place where you can immerse yourself and concentrate with less disturbances than other service jobs. I have met a few people who certainly have the traits, so I would not be surprised if they are on the spectrum. Without exception, they are exceptional and very talented. Highly intelligent and very fair. Of course, their social skills are not great.
I read a book, The Complete Gulde to Aspergers, which is a very good, yet complex book by Tony Attwood. Interestingly, he said that when he first diagnoses an aspie, he says congratulations. Aspies are typically far more talented that NTs.
