Our brain generally relies on the first system way more than the second, to the point where what we think of as logical decisions are often actually intuitive ones that we then rationalize after the fact using system 2.
This is basically a power saving trick: Rational thinking uses way more energy than intuition.










There’s also the fact that medical devices undergo a ridiculous amount of testing. A friend of mine works for a company that makes medical devices and even getting some non-essential UI changes to production took about two years from when he was finished implementing them. Critical stuff can take longer to get certified.
This is all so that nobody builds the next Therac-25, a radiotherapy device that, due to design flaws, could inadvertantly be turned into a literal death ray.
The upside: We can assume that any duly certified medical device is as safe as is humanly possible. The downside: Those medical devices may as well be made of solid gold as far as the price is concerned.
I hope you can get this sorted without having to spend a ludicrous amount of money. Perhaps the things can be fixed. Probably not, the day things are designed these days, but I’ll still hope.
