If I could tap into the quantum realm, I wouldn't ever have to worry about making typos or grammatical mistakes in my blog posts.
With reverse causality, I could ensure that all my posts are perfectly written, even to the standards of George Orwell. Should the English vernacular drastically change, it could still be written perfectly. I'd only have to decide how I wanted to reword things to discover that it has already been reworded as such.
The only stipulation is that I would have to, at some point in the future, actually make the changes. Or get someone to do it for me.
"Anything that happens happens, anything that in happening causes something else to happen causes something else to happen, and anything that in happening causes itself to happen again, happens again. Although not necessarily in chronological order." Douglas Adams
