Respectfully, I don't think you took away the correct implications. Specifically in the implications section of [1]:
"The key to effective intuitive decision making, though, is to learn to better calibrate one’s confidence in the intuitive response (i.e., to develop more refined meta-thinking skills) and to be willing to expand search strategies in lower confidence situations or based on novel information."
and
"Relatedly, it also means we should stop assuming that more conscious and effortful decision-making is necessarily better than more heuristically-driven intuitive decision-making."
I would say that while the article makes very interesting objections to the S1/S2 thinking framework, its objections are that they are far more intertwined as measured. However, the article still very clearly agrees that S1 is lower cost than S2.
