I am wondering if the Quicken developers have thought of this but..
To talk to OPENAI and see if they would allow Quicken to give CHATGPT the entire source code of Quicken and tell it to flush out as many bugs as it can find and also to propose the solution to each bug it found.
And then, the developers would investigate each instance that CHATGPT reported manually and see if the bug is valid and if the proposed solution is valid
just a thought :)
