The speaker says evaluating a neural network's predictions of long-term outcomes is difficult without at least one long-term observation.

“what is possible has fundamentally changed and let's very quickly then reorient around it and again you have to do it you have to really think through all the all the consequences right and all of the implications and that one of the you know if you're thinking about long-term studies people and my question of like you know is this neural net actually in terms of what's predicting the stimulation actually accurate for long-term outcomes it's pretty hard to not have at least had you know one long time tick”
