Oh, I don't disagree at all. The reason I don't think it belongs on HN is because "It's essentially a collection of unsubstantiated claims that would likely have no impact to policy even if they were demonstrably true because the driving factor is human safety and not efficacy or ease of teaching." That has nothing to do with whether or not I agree with those claims, although in this particular case, it just so happens that I do.
