I can see a usecase for where you don't know where to start or search with, and then verify with actual searches.

I recently used it to explain for a friend what is the difference between wheat and ale beer, and it gave a very good summary. With DDG I might not get a direct explanation and would need to read a few articles and then word them in a comprehensive way.

You can disable the power button shortcut. Search for something like "emergency sos".
