we might know what ways were better than others when it comes out in the wash in decades to come
there's been a couple of places do it differently and loads of data - so, there will be research for years
lets all hope like hell that we do learn heaps - because if we don't - there's no point to any of it.
the biggest problem I see is not that we won't learn lessons -
we actually are pretty good at learning stuff -
what we are bloody dismal at is executing changes on the back of that learning
we just seem to refuse to do the most obvious things - often just because we take the cheap road or the easy road or the road that most people 'think' is what they want - but, there's actually solid evidence to say it's the shit road
we are very good at learning and very bad at applying lessons
