I don't really care to get into a philosophical debate about what's good or what people should use.

I use these tools daily and they help me immensely. If you prefer Googling for docs, browsing stack overflow, or even flicking through textbooks to find the answers/materials you need - that's great! Do what works for you. I value my time slightly more than that and prefer not to remain stuck in the past.

Perhaps you hold all the information you need in your head like an oracle and never need to learn new concepts or ever forget syntax? Wonderful. The rest of us aren't so naturally talented, so have found these new tools super helpful.
