What would be the implications of such a society? Just because someone is needed and wanted does not neccesarily mean that they feel fulfilled. These "dumb" technical advances do alleviate the need for people. However, they do so with tasks or jobs that are often repetitive and mindless. Sure, more complex occupations don't ensure fulfillment, but they engage the mind in a way that it's arguably easier to find fulfillment. In this way this technology moves us forward to a society where we purse roles that optimize our sense of fulfillment.
But, there are caveats to this as it assumes that everyone can find a form of income with their own set of circumstances. Technology empowers, but who and how we empower is the puzzle we need to solve.
