If I've read the OP correctly, it would appear that information theorists would say that since the definition of individual is the effect of propagating coherent information forward in time, the "end" of the individual entity would be when it ceases to cohere information forward in time. Given everything "dies," and in this proposition in the blog post individual entities (living units or not) cease to propagate coherent information forward, the implication to me is the entity that is, "I," will also de-cohere.

By defining an individual unit of something as information, they've taken something we only had metaphors and analogies for and concretized it as a category of things that behave like information. I've applied it to something else we only have metaphors and analogies for, and am sounding out whether it provides any additional insight.
