XNA was a wrapper around a specific set of DirectX 9 technologies, coupled with a few portable utilities.
Monogame is an open source implementation. It is dead, or not dead, the same way DirectX 9 is either dead or not dead. It is not dead in that it continues to work just fine. It is dead in that it isn't getting updated to DX10 or DX11 or DX12.
You can continue to write software using DirectX 9-era tools and software if you choose. It was most viable when it was released, was still viable in 2007 or 2010 when people were asking if it was dead, and is still somewhat viable today in 2016. What you build with it will still work for years to come, but there are newer things available.
What are those "newer things available" ?

Dead or not... XNA / Monogame are great tools to ease the learning curve into game development. This will help to understand the game structure and how it all works and give you a good idea on how to write a game from scratch using DX9 or a library in SFML using C++. It is all up to you, but learning is never a bad thing.
Im with you, still a way to learn. I'm not against anyone, just need to improve myself.
