For some reason I feel a few people in this thread are "on edge"

why do you think that is?
I think MyGuyTy has some very valid points and I don't believe he is being pessimistic at all...but rather, realistic. I don't know what will happen to the hobby in the next 30-50 years or after that, but I think what he is saying seems very logical...to deny it, seems like you just don't want to think about it.
We all know that the younger generation is not into cards like they used to be and I don't know one kid under 18 except wazoo that does! Twenty or so years ago, card collecting amongst kids was so popular...but now it is mostly dead. So what does this possibly say for the future of the hobby once our generation has passed? I don't know the answer for sure, but unless A LOT of younger kids get moving, we should see a decline for sure.
Since the '90's or so, it has been a wreck for kids to collect because of the prices and a lot of card stores are long gone. Things aren't that simple or fun anymore and if no one is there to present this great hobby of ours to them, then where is it going? Certainly not up, right? I'm sure there will always be buyers and sellers, but I highly doubt the demand will rise IMO. I love this hobby and I for one do not want it to decline, but it kind of seems obvious when you think about it.
There's no doubt that it should stay steady for a good amount of years, but for how long? We only have a small sample size of card collecting overall (130-50 years) and we're already seeing the younger generation stray away.
