The question of « scientism » should be a dead duck by now, and I wish it were. Louis Althusser went through a scientistic phase, but was able to overcome it in his ongoing self-criticism. His later aleatory materialism is already a form of « quantum » thinking, very much indebted to Deleuze.
Laruelle is indebted to both Althusser and Deleuze, without having given proper acknowledgement. Laruelle’s scientism is a throwback to the earlier Althusser, and his own self-criticism is only partially accomplished. This problem of scientism highlights the dogmatic, nostalgic, monistic side of Laruelle that I have always rejected.
You will get no satisfying answers to these questions from the official Laruelleans. Raising the question of Laruelle’s scientism with insistence will only get you condescending denialism, or get you ignored, banned, or insulted. OOO bis!
