The wiki may die before this, but that doesent mean it won't be forgotten. at least, it will be remembered for a while. perhaps just in Long Term Memory Graveyard.
When I say Long Term Memory Graveyard, This is what I call where your brain puts a memory in long term memory, but you don't end up remembering it till a long time later.
The SCP wiki has been going on for over a decade. You could say that it's different because wikidot is different than fandom, but there are some fandom wikis that have also lasted a long time. We have a shot at lasting for a long time, but we'll have to become a little more popular for that to happen.
