@lina the simplest solution is usually the best, 5$ shovel...

jokes aside, i see this around me as well and believe is more about "don't make me work since i am close to retire". i see this in people close to 60 taking care of providing for their family and rewriting something in Rust "just because" will not change anything in their routines.

keep it up and wait until they retire when you will be the second in command and take charge. It is the most painful, i know.
