If nothing else, the fact that many people write anything with ink and brush helps to sustain the calligraphy culture. Nowadays, to many (if not most) of them the new year kakizome ritual is the only occasion they practice brush calligraphy in an entire year.

Various businesses provide paid service called 見守りサービス to have someone (or a machine) check up on you. The idea is to detect health emergencies early enough and act on getting help, in case family members and neighbors can't. Not that that is the best option, but at least money can help to some extent.

It looks like this is what it does essentially:
let luminance = (0.2126 * avg_r as f32 + 0.7152 * avg_g as f32 + 0.0722 * avg_b as f32) as u8;
let character = match luminance {
0..=31 => '#',
32..=63 => '@',
64..=95 => '8',
96..=127 => '&',
128..=159 => 'o',
160..=191 => ':',
192..=223 => '*',
224..=255 => '.',
};
