Thirty-five years ago you could pretty much hold the language and most of its standard library's names and usage in your head and what you forgot could be contained in a book which hopefully had a good index (no Google back then). It's not the case today with large libraries having thousands of classes, tens of thousands of methods and properties. It doesn't make sense to search for everything day in day out. Even the base languages themselves have grown in complexity quite a bit.
Don't pretend that the "young developer" would know what to do without them just because they don't use an extension in an IDE. They'd just Google all day long and waste time they don't need to waste instead of focusing on resolving the problems they are paid to solve.
