It's the way of the modern world, not just a computer thing.
Cars are the same, 20 years ago people knew how to fix their own cars and the guys who worked at the parts stores were knowledgeable and friendly, now its all big stores like Halfords where you get some kid who only knows nothing about mechanics and only about putting big wheels and a loud exhaust on it.
Music is the same, once it was all local record stores where you could spend the day listening to a stack of vinyl and chatting the the sales guys about the newest releases. Now its all an international money making machine with big impersonal stores and internet downloads. (Same thing for books).
I think we just need to be happy that we were lucky enough to experience the beginnings of the computer revolution in the 80s. Computers have just become an ordinary consumer product (like music and cars for the most part) and hence a lot of the magic has gone, at least from what we see on a popular consumer level. But if you dig a bit deeper you will always find the niche genres where there is still exciting/nostalgic/innovative stuff happening that you can get involved in.
