I don't think that was the grandparent's premise, but I actually think that it's not unreasonable to expect experts to be able to boil down their ideas for non-experts.

We know it must be possible, because they themselves arrived at that point in an abstract "graph of knowledge" starting from a blank slate at birth, so going the other direction is (at worst) merely backtracking that path. However, most experts know enough other nodes/edges in the graph to identify shortcuts from their conclusion back toward the 'beaten path' that most people would know.

I often argue that if you aren't able to articulate the core idea of your research to someone outside your field, you might not understand it as well as you think you do.

(Re: the grandparent) When communicating with the scientific community, however, it's not unreasonable to be as precise as possible to convey the idea accurately to fellow experts. Replacing scientific papers with blog posts is not a good solution; augmenting scientific papers with blog posts might be appropriate.
