Boeing slams the Falcon Heavy rocket as “too small”

Heh - so the Falcon Heavy has launched a Tesla on its way to Mars, but the Boeing SLS which hasn't flown yet is more capable of "NASA's deep-space needs"???

Are "NASA's deep-space needs" as non existent as Boeings rocket? (Given the current administrations record of funding science, that could easily be a true interpretation, sadly...)

Also, how cool is it that the SaturnV is still the most powerful rocket ever flown? Those '60's rocket scientists were genuine heros...
