I guess I'm extremely optimistic but as I said, I don't really mind if I won't be able to run a node at some point. Why should I care anyway? The cat is out of the bag and if bitcoin eventually become too centralized and allow censorship then I'll just move to the next uncensored blockchain just like I will do if the bitcoin blockchain doesn't scale enough.
Taking responsibility for your own future implies that you do care about the long term impact of your choices and actions. I know, we all grew up in this consumerist mindset and are not used to things like Bitcoin, so we are still projecting the old thinking onto this new technology. But I'm glad that many now realize that this "Game" is "Just A Lil Bit" different and being conscious and responsible is "How We Do".
Moving to the next (good) blockchain might prove to be difficult as PoW systems are extremely hard to duplicate in order for them to remain secure and independent from each other. We only have a few decent ones to play with and losing the most prominent example and the pioneer of that technology may have devastating effects on the whole crypto-verse in general. I would rather have another similar system make a risky move and experiment, while Bitcoin enjoys its heavyweight champion position and the sense of stability and trust that comes along with it. The leader only responds when being challenged in its area of expertise.
