I watched the talk which is pretty much of a rehash of what he has previously presented. What I came away with is this is a much more difficult problem than what he thought it was a couple of years ago. At one time he was hoping for a quick resolution, but now it seems that the more they learn, the more difficult to understand the disease is.
He mentioned again that they looked for a viral cause and haven't found one yet.
He talked about potential treatments and mentioned that if they can't find an approved drug that works it will take 20 years and a billion dollars to get one.
My take away from the talk is that a cure, or at least a treatment for this illness is farther away than I was hoping for. I will keep hoping for the best and expecting little.
