Comments like that are a bellwether of the place they’re posted in. People will hedge their comments whenever they fear there is a sufficient concentration of “well, actually”s in the audience.
I think it's oversimplified because there would need to be a long explanation on what is meant by "self", which the commentor very wisely put in scare quotes.
To the parent: actually I think this "death of decoherence" pretty closely matches the Buddhist doctrine of interdependent arising, so not sure about the disagreement there.
The only part that's missing is "...with the goal of avoiding suffering".
