Could that change, though? It's 20% slower now, but could it be 10% faster than the human in the future? 20% faster? Or even 50% or 80% faster? I really don't know, but it's plausible.

Even today, consider that the GP's quote is trading human time/energy for external time/energy (even if the latter is greater). Manually doing a complex refactoring can be a tedious, annoying, draining, error-prone process. I don't enjoy it, and after doing it, I'll be annoyed and prickly and not feeling a bit intellectually dulled. If it takes me "only" 2 hours to do it myself, but takes the LLM 2 hours and 24 minutes, I might logically make that trade if it meant I could keep myself sharp and un-annoyed, and also perhaps get in some light reading while the LLM is doing its thing.

(In fact I am literally doing that exact thing right now, having an LLM do a refactoring while I write this comment. Maybe dicking around on HN isn't the best use of my time, but it's better than tediously shuffling existing code around, even if I can do that faster than the LLM.)
