>Popper’s idea that scientific theories must be falsifiable has long been an outdated philosophy. I am glad to hear this, as it’s a philosophy that nobody in science ever could have used . . . since ideas can always be modified or extended to match incoming evidence.
I don't know what is the context of this quote, but this sounds like a deep misrepresentation of Popper's position. As far as I know, he explicitly addresses the issue of ad hoc and auxiliary hypotheses. Unless this is part of a bigger point about some the "fine-tuning" of theories i.e. just how much the main proposition can be off the mark given the additional hypotheses.
