When I tell my colleagues at work that we're already in transition to a post capitalist society, they think I'm crazy. The automation of tasks by machines and digital software has (and will further) reduce the need for labour and as a result less (for profit) firms will exist. Wikipedia, filesharing websites etc are already showing a model of business which serves the community. Ultimately a post capitalist society will just be a society where capitalism is less prevalent. Hope this answered your question.
