That's one of the key points of the article. You can't reasonably extrapolate that the goalposts will always move. Just because science is able to discern more than we expected in the past and will continue to do so in the future, doesn't provide us with any concrete reason to trust that its eventual scope is equivalent to the full breadth and depth of potential understanding. In fact, quite the contrary since the great virtue of science is that its scope is limited to empirical, quantifiable truths. You can avoid that uncomfortable question by proclaiming empirical reality to be the only reality, but that's a metaphysical claim with no greater merit than its opposite.
