The smartest ones are maybe not the ones providing suggestions?

Then again, it's fun to speculate, and what are these threads for if not to provoke thought? Maybe it's fine for people to imagine and try to put themselves in the place of the professionals working on the problem. You can interpret the comments here as an indicator of dangerous human hubris if you want, but I think most of the people here understand that they can't do any harm by posting naive speculations on HN.

In my opinion, we should save our outrage for people who make an active attempt to be taken seriously and affect the actions of more qualified people, such as the guy who posted the bizarre (and possibly satirical?) account of his attempt to build a system for guiding doctors' treatment decisions.
