That looks like a real pain in the ass to solder with a 0.35mm pin pitch.

Not something I would try to hand-solder. Not something that feels relevant for me as a hobbyist either, although it's very cool.
Imagine the arduino-clone boards with these... For very small hands!
Well I guess the era of nanobots isn't far then
Most embeddable medical devices need wireless to share out data and get OTA updates. Unless you're doing wired things, in which case MCU size may not matter.
As cool as the TI is, I'd look at the new SiLabs BG29 for processing + BLE: https://news.silabs.com/2025-03-12-Silicon-Labs-Unveils-BG29-The-Future-of-Bluetooth-R-LE-in-Miniature-Devices
On second thought... a medical device that goes in one end, collects data, and comes out the other end. OK, that may not need wireless... and it better be small.
Aww it's a bebe!
