This is as ridiculous as saying an electrician will forget how to correctly wire because their wire cutters are too good.
I used to be a build-my-own IDE person via VIM. After using PyCharm and realising an IDE is more than an editor, I realise the productivity gains every day.
If I need VIM or something else, it's just another tool in the box and the partisan fist shaking has no place in a mature profession and trade.
