I chose "until" specifically because finding a good use case does not justify any of the shenanigans that happened before that discovery. The word "when" doesn't carry that connotation, and "unless" doesn't either - though I'm guessing you chose it because it implies we may never find one?

We may as well do, but unless that actually happens, it's going to continue being just wishful thinking.
