Eliezer:

"I admit that when Wallace talks about the number of observers being unmeasurable because decoherence gives you a continuous tube of amplitude rather than distinct blobs - so that I'm not so much twins, as smeared - he manages to unnerve me even more than I was already unnerved, with regards to my feeble attempts to count observer-moments. But, ultimately, you could construct the same situation with Ebborians, so..."

How would one construct a "smeared Ebborian"?
