Varoufakis is a great economist and his placement as the Finance Minister is a smart move from the new government. At this point I would like to suggest reading
To Future And Back by I. Pitsouli[1]. Somewhere in it, there is suggested (or prophecized if you wish) that in years to come scientists will replace politicians in governments. Well, that has already started happening and is right IMO because science is closely related to philoshopy which in turn by definition deals with problems related to reality, existence, values, etc. ie. the everyday problems most politicians seem to ignore nowadays.
ps. Varoufakis definitely needs to revisit Bitcoin though[2]
