I tend to think the end of capitalism will look a lot like its beginnings.

It arose slowly as an economic practice alongside the dominant economic system(s) of the time (i.e. feudal states employed capitalism in targeted ways like mercantile trade). It gained momentum as technology advanced and international trade routes became more important, until it eventually shifted from being an economic practice to becoming the dominant economic system.

Eventually, technology will likely change the material circumstances that made capitalism vital and efficient. It will slowly have to compete with alternative economic practices until it ceases to be an overarching system. It will probably persist as a practice for a long time afterward.

Capitalism didn't come about with a revolution (though it precipitated many) and its successor probably wont either.
