I've heard about a few of these companies around, including at least one in my country (The Netherlands). They even were on television at one time where they talked about ASD and employment.
The notion is quite interesting that they want people on the spectrum since they might be better at certain tasks. However, what bothers me is that most, if not all, are geared towards IT. I'm not one of those IT aspies at all. I mean, I know how to troubleshoot my home network and then some more technical computer related things, but thinking I'd be interested in doing any job that involves computers would be a stretch.
On the other hand, perhaps if I was given an opportunity; learning C++ in 6 months shouldn't be that hard (ducks, just in case any programmers disagree) if it would involve employment and a good income. But as it is now I don't really have any motivation to do so for my private situation, nor does it look appealing to just do as a "hobby".
What I found interesting when I saw the program on television about it is that the company here, did hire aspies, but from what I understood they all had university level education anyway in the field. So in a sense it still fails to accommodate those who already have issues getting through education (read; dropouts); even though education is sometimes seen as a "light" version of employment, it makes me wonder if governments and other "companies" aren't actually a bit out of touch with what's quite common for people on the spectrum, cause I'm somewhat convinced that if I were to be able to make it through college or university, I wouldn't have as much issues getting a job; having an "aspie-job" would just make it a bit easier in terms of support and guidance to maintain a degree of sanity though.
