It requires exactly the transition that Marx posited - redistribution of wealth to those who's livelihoods have been automated away. Taken to the limit of automation, that's pretty much anyone who's living is dependent on labor (this includes programmers).

No. He key idea of Marx was that the person adding value should own the means of doing so. Which, if you think about it, is exactly what's happening. The key element of value creation is the mind and that is owned by the person. Marx has nothing much left for people who _do not_ add value simply because back then that meant being "the problem". He who does not work must not eat. But what if there simply is no need to work? You should not try to apply social theories of late 18th century to the one of early 21st.
