While it doesn't really change the meaning of the article, it's pretty clear that it isn't the calculator app leaking memory, per se.

Tahoe seems to have some system/API memory leaks that while they might get attributed to an app, can manifest against any app on the system. Lots of different apps have been hit by this. Personally I had an 80GB Messages app problem twice now.

Software quality is a problem. Tooling should improve this, and Swift, Rust et al should improve the situation over time, though it's a battle as software has gotten exponentially more complex.

Having said that, it's bizarre how this somehow turned into an AI screed. I doubt a single one of the noted bugs had AI play any part in its creation. Instead some weird confluence of events, usually with human beings making assumptions, happened and it occurs just randomly enough -- as with the Tahoe bug -- that it isn't caught by normal prevention techniques.
