A friend has journals a few years old and on the right 2/3rds of the pages the writing is nearly gone (theory being maybe that side got warmer, but not certain)
Most prefer the t:slim X2 with "Control-IQ" (their hybrid closed-loop: https://www.tandemdiabetes.com/products/t-slim-x2-insulin-pu...), which is FDA approved for ages 6+, and works great.
The bleeding edge is the Beta Bionics (https://www.betabionics.com/) bi-hormonal system (insulin + glucagon), currently in clinical trials for ages 6+.
Tidepool is also trying to take the loop project and get a version of it FDA approved.
Both of the open source projects require you to do the work and actively take control of your setup (a cgm plus pump plus phone). They have really nice support communities. I would never go back to not using Loop.

My third favorite thing is that I’m pretty sure the movie wouldn’t have made its premiere if it hadn’t been for some last-minute Python I wrote to fill the last drive to rush out the door.
God, was DD a good place to work.
The vfx business was and continues to be a "challenging field to work in", but man what an incredible experience it was working there.
