Context, context, context - which those of us stating 32 GB is overkill have established - does have notable exceptions.
There are outliers on any bell curve. Those who are using software that does 3D model rendering with the ability to rotate very complex models in 3D space will murder ram. Many specific games, particularly multi-player online games with wildly intensive graphics will murder RAM. And there are other situations.
Those exceptions are that - exceptions. For most typical usage scenarios for most users, it's overkill. If you are someone who is in an exception situation, it's not. This should really go without saying in a venue such as this.
