I've come to understand that SSE (for the time being) is safe, because any other type of ride would compromise the structural integrity of disney's most photographed monument. Last time I was there (March 04) I asked as many CMs as I could and they all unanimously declared that SSE should be good for at least another 5 years. There is no need to worry quite yet.
That said, I've been doing heavy thinking on the subject of Epcot Center recently. I've decided that although it's sad and depressing, the best thing to do is to let go and accept change. The memory of Epcot Center will live on in us all, and therefore it's something special that we share, a love of a place WE knew. Millions of first timers come to Epcot yearly, and will never know of Epcot Center...it is ours.
Don't let the memory die. But try not to get caught up in the past - it makes it tough to enjoy the now. Epcot as it stands now is still a pretty cool place. I'm tired of going there and spending all of my inward thinking on pointless lamentation. I want to enjoy the enjoyable. If nothing ever progressed we'd still be using wax candles as a primary light source.
