There are a number of established residential architectural styles in the United States. Victorian. Colonial. Ranch. Split-level. And the McMansion.

According to this Ngram viewer result, the term McMansion entered use in the late 1990s and then its use went up a lot between 2002 and 2011.
This roughly fits with what I found in my 2012 article on defining McMansions. The multi-faceted term described a newer wave of houses in a particular cultural moment.
What the Ngram above shows since 2011 matches what I have informally seen about McMansions since 2011: they are now just part of the landscape. They are not new. Americans build, sell, and buy them. They still are derided. There are dips up and down in the Ngram viewer but it has not changed much since 2011.
New residential styles will come in the future. Changes to society, the economy, housing, and preferences will lead to new designs that will then be assessed and critiqued. Perhaps they will bear some resemblance to McMansions, perhaps they go in completely different directions. The McMansion will live on among existing and new housing styles.
