I would consider computers to be my 'special interest'. They've not always been in my life, though - I didn't use a computer until I was mid-childhood - and I was definitely a social wreck before that!
The computer has made things easier, definitely. It allowed me to escape from a world that I've never felt comfortable in. Honestly it's brought me more social opportunities, too, but at a comfortable pace and without pressure.
And the older I get, the easier life becomes. Now I can do all sorts of things online that others couldn't do in the past - banking and managing my bills, for example. And so many other things that I might have had to use the phone for, or speak to people in person for, which would have been so difficult. These are day-to-day things that, if I'd grown up in an earlier generation, I would have really struggled to cope with. I consider myself to be 'high functioning', but if I'd grown up without computers then I expect things would be very, very different. Every day I'd be on high alert all the time from needing to be social - I would be so anxious. I hate to think what that would be like. I might have been a long way from high functioning!
But, thanks to computers and technology, life gets easier for me every day. I can now do my shopping using a hand held scanner, without needing to speak to another person. I can order food at McDonalds using a touch screen so that I don't have to script my order in my head and then try and communicate it to someone. As technology becomes more widely available then I guess for a typical person it could be something that 'cuts them off' from opportunities for communication, but for me it's saving me from extreme stress and anxiety every day. And it's not the computer that's causing it - the computer is helping with it, it already exists.
