I think you're pinning on incompetence a lot that has more to do with cultural mores. This doesn't seem remarkably better across the board to me. It seems neat to the technologist in me, but it also feels extraordinarily fussy, an accommodation for the weak or incapable.

I recognise we should probably move to bidets, but I wouldn't look forward to the sidelong "is he a bit weird?" glances from guests. Warmed seats is a bit like fuzzy earmuffs: probably an improvement but something I feel like I shouldn't need. In some sense, I think trying to improve a toilet at all feels weirdly epicurean.

I find this vaguely embarrassing to write, I'm not a particularly macho person and I don't like to acknowledge that sense of masculinity circumscribing my actions. But I think it would take a hell of a marketer to get me past that, especially at a steep price point, nevermind people who are openly manly.

[0] Japanese toilets were long the butt of stand-up comics' jokes. I remember one such comic ending with the punchline "I'm being raped by a toilet!"
