K1JT has just announced FT4, a new mode for digital contesting. Initial release in a week. Interesting stuff, it’s 2.5× faster than FT8 and super sensitive. https://sourceforge.net/p/wsjt/mailman/message/36646405/ (Let the hating begin!)

Not seen any “it’s not real radio” yet, but it’s only a matter of time.
