Quite the opposite, people used to be way more replaceable in the 80s than today. The real issue with the latest technology developments (say from the 80s) is that they require more and more cognitive skills to be adopted, which makes it harder to replace a worker while preventing a larger and larger part of the population from enjoying these productivity gains. This explains a large part of income inequality.
