it's not going to stop, and those who complain about it without curiosity about why it's such a valued language feature are doomed to suffer until the end of their careers.

at the same time, I'm somewhat interested to hear a further defense of this idea that newlines and spaces are "invisible". Is this invisible in the sense of neutrinos, or in the sense of wind blowing in the trees, or in the sense of the vacuum of space, or what?

For my part, I seem to have no trouble "seeing" line breaks, spaces between words, etc.
