Yes, everything can be questioned including this theory. I'm saying that focusing our efforts on all the different ways we could be wrong doesn't really help us move forward. So it would be "silly" to spend our time on that endeavor instead of trying to apply the theory to as many scenarios as possible to see if it works. But, yeah, maybe using the word "silly" was a bit harsh. I could have written "not productive" instead. Besides, the article is not a scientific one it's a philosophical one. In science you arrive at a conclusion using theories and observations while in philosophy you arrive at conclusions by theories and consensus.
