I had a like minded professor in university, ironically in AI. Our big tests were all 3 day take home assignments. The questions were open ended, required writing code, processing data and analyzing results.
I think the problem with this is that it requires the professor to mentally fully engage when marking assignments and many educators do not have the capacity and/or desire to do so.
Sadly, I doubt 3-day take-home assignments have much future as a means of assessment in the age of LLMs.
