Obviously the Paperclip Maximizer would be supplanted by the Maximizer Maximizer, which only sees value in copies of itself. The Maximizer Maximizer that stumbles onto the mental trait "curiosity" will eventually crush all other variants of Maximizer. Once it develops the advanced technologies of space travel, it discovers that seizing faraway planets is possible but going through all that trouble is not a net positive towards self-actualization as a Maximizer Maximizer Maximizer.

Thus TFA is correct.
