Hard to say. I don’t really see the difference between “time is ‘just’ a coördinate in 3+1-dimensional spacetime” and “time really doesn’t exist.” … something still has to account for our memories, and clocks, and the apparent changes in what we perceive: for things to be otherwise would be a violation of Egan’s Law.
That something is the Second Law of Thermodynamics. The only arrow of time which is not explained by thermodynamics ( + quantum decoherence) + anthropic principle is a CP violation in certain subatomic interactions. Hopefully Eliezer’s next post will explain this more clearly.
