The spiral doesn't end, communism will not be the end of history. Humanity will always have problems and struggles, be they here on Earth or among the stars. Communism is going to be the end of class struggle, but everything is in constant motion and all development is driven by contradictions. The creation of a stateless, classless, moneyless society, "rhymes" with early communism that lasted for the bulk of human history. At the same time, it is forward in history, we are not returning to hunter/gatherer lifestyles but instead will stitch all of production and distribution together in one unified whole, scientifically planning how we develop in order to meet the needs of the people and advance collectively forward.

"Ideal communism" is not a thing. Such a notion draws more religious, holy implications than anything else. Communism is a real, material system naturally evolving out of socialism, itself evolving out of capitalism.
