I agree, impressive

I'm quite skeptical. :) I'm not in the know but to claim "subatomic precision" and then show an image with less accuracy than regular ultrasound doesn't inspire hope. And it would be more impressive if they did actually show their experimental setup. Their 1.4k m/s require a liquid medium, but it's a single ring and the body is said to be lifted through it. Given the images shown and, I assume, the need to reduce any bubbles and drips, it would have to be a at least 2+ m tank and you'd have to hold your breath. But maybe they don't care about bubbles and such. "Less than 12 of these systems can outperform all MRI machines on Earth" - riiiight. I don't have to be submerged in a liquid medium when doing an MRI though. Here just the preparation and the clean-up steps might easily take longer than an MRI. God I hate nothing burgers full of empty promises. It looks more like a Max Cooper video, sounds like one as well (which isn't a bad thing).

Right, they did release another video that kinda shows the setup. It is indeed a vertical column with a lift, but a person isn't lifted during the process - they are submerged. Still doesn't solve the bubbles problem though.

I think a nice thing about MRI is that you can keep your hearing after it

I ditched my kindle for an e-reader with KOReader a while back. KOReader takes some setting up, but once its set up its better than the kindle software imho. For sync you need some software running on a server somewhere. I've been happy with Kavita for accessing my library across devices and syncing reading progress. I have not tried syncing of notes and highlights. Maybe not as frictionless as the Kindle ecosystem, but not being under amazons thumb feels good! Oh, and you can install KOReader on you Kindle if you "jailbreak" it.

Just in case - if the software readers that you use store notes/position/etc. in files, you might have luck syncing all that without any servers, via SyncThing.

I don't think locations/notes etc are saved within epub files

I didn't mean within the files that you're reading - just within some files that are machine-independent.

https://github.com/gitalexcampos/highlightsync.koplugin writes highlights and notes to a file that can be synced with thirdparty software
