Bull****. That is spin and an outright lie.
Agreed
Modern aircraft are smarter, more integrated, and have in depth on board maintenance systems.
As a result, they tell you every tiny little thing that is wrong with themselves, then petulantly sit there displaying some EICAS or the like message that means you can't dispatch until you clear the message, perform the FIM task to check it has gone, do an RTS.
The older aircraft might have been steam driven, but they didn't throw their toys out every time a widget farted the wrong way.
