All of the industries I've mentioned are already international. Law firms have offices around the world and routinely export work. Audit firms too. Your arguments about momentum of software also equally play to the big law firms and audit firms, if not more so. These firms have been gorillas for a very long time. For perspective, PWC is the result of a merger between two large audit firms founded in 1949 and 1954 respectively. Microsoft was founded in 1975. PWC is a worldwide company employing 236k employees. Microsoft only employs 124k. Admittedly Microsoft has a revenue of ~90 billion vs PWCs mere 37.7 billion. But I'm not seeing why one is fundamentally different than the other.
