Thats funny

I’m not an expert in that, But I also came to comment about something like zfs. I’m currently using btrfs and it works great for backup. The idea is that the filesystem itself contains the information what changed as far as I understand. And therefore the send operation are very lightway. As they are so lightway it would probbably be possible to also just do manuel sync(e.g. when you finished working for the day. However I can currently not think of abdirectional way where you have changes at both places and then merge them.

I think I like that the progress that happens actually make sense and makes my life better. Of course there is almost no progress that you can feel I’m this technology over the course of one year but that eInk in gnerell became a think over the course of my life still amaze me everytime I think about it

Yeah I 100% percent agree. But as far as I know most of the eBook reader also slow plain ePub or PDF and than you can often find these online or order them directly at the publisher. Sometimes you buy them at the publisher there will be only a signature and no DRM.

E-Ink and Ebooks in generell. Maybe not all the shitty Software/DRM that often comes with them but the technology itself is amazing.
