I might also depends for how long the developer has been using the tool. At university we first learned to program with pen and paper to develop memory and thinking habits before doing everything by hand with only vim and after that using and IDE after +6 months to let the habits develop. Maybe if a developper starts learning straight with copilot, some habits will never form and things will never go into long term memory ?
