@JoranJongerling@academicchatter I just hope it doesn't happen :-D Also most of those inactive projects tend to be small (stat help for clinical investigators) and few are highly time sensitive, so it is usually easy to prioritize if there are conflicts.
I currently co-teach one class each year in two language mutations for ~250 students total + some practicals. The class was new last year, so still modifying and building up materials and infrastructure, and it is a huge time sink.
