A couple of weeks ago, I asked google, ordinary google search, how many times the letter r is found in preferred, and it told me 2. This century has taken quite a bitter turn against those of us who think that the 'enough' in 'good enough' ought to exclude products indistinguishable from the most grievously disgraceful products of sloth. But I have also lately realized that human beings, brains, society, culture, education, technology, computers, etc, are all extremely complicated emergent properties of a universe that is far beyond our understanding. And we ought not to complain too seriously, because this, too, shall pass.
