It’s fair and informative though it doesn’t explicitly spell out that his conception of communist society was one with production and distribution directly for use and so not for sale (and so moneyless) and that planning and calculation should be done solely and directly in kind without the need for a common accounting unit.
Interesting that the interview says that Bordiga wasn’t dogmatically against contesting elections on principle. But of course he still envisaged the socialist revolution as an armed insurrection led by a vanguard party. Come to think of it, that’s not brought out in the interview either.
