Yes. Preferences and ethics are not consistent among all living humans. Alignment is going to have to produce a single internally-consistent artefact, which will inevitably alienate some portion of humanity. There are people online who very keenly want to exterminate all Jews, their views are unlikely to be expressed in a consensus AI. One measure of alignment would be how many people are alienated: if a billion people hate your AI it's probably not well aligned, a mere ten million would be better. But it's never going to be zero. I am not sure "a lot of books have been written about it" is a knockdown argument against alignment. We are, after all, writing a mind from scratch here. We can directly encode values into it. Books are powerful, but history would look very different if reading a book completely rewrote a human brain.
