I had a similar feeling. I think the point that TFA is making is that our world is changing quickly and profoundly enough that "we've always done it this way and we know it works ok" is not as useful a heuristic as it might once have been. We shouldn't thoughtlessly discard proven ways of doing things, but we may need to update the weight that we give them. What worked well in 1990 isn't as likely to work today as 1960's practices were in 1990.
