Yeah, at least you acknowledge enough for me to say you're being reasonable about it. I just disagree with Brad, because as I said it was a part of the plan from the beginning to increase blocksize. It seems like we agree on everything except for what is likely to happen for Bitcoin's development and future; I'm willing to deal with this, but I do feel firmly that these obstacles will be tackled at some point. Only greed and fear are keeping Bitcoin in its current state.
I don't know what will or will not happen, nor whether all the "experts" (Like Brad!? and many others!) are right or wrong. I do believe though that they cannot know what is going to happen. What everybody is doing is called "guessing", a well known activity that people engage in but pass it on as an actual forecast of some future event!
What we do know is what has happened up to this point. We know that bitcoin has not entered the mainstream as a payment system. We know that it has developed much more extensively as a store of wealth. We know that there is a growing number of speculators trading bitcoin for short term gains. We know there are developments in the pipeline that will tackle speed of transactions, cost of transactions, etc. but we cannot know how effective these will be. In fact, we know very little and we too are just giving our best guess. We are as "expert" as "the experts".
