Taking this quote out of context is impressively dishonest. It would be incredibly inaccurate to describe Elon's history of winning big as "occasional", and for that same reason it would be incredibly surprising if Charlie Munger described Elon's career this way with no qualifiers.

Not surprisingly, he didn't. This quote is the end of a much more nuanced statement to conclude the point that he generally prefers to invest in operators who take less risk.

Regardless of your opinion on Elon, this sort of manipulation of reality damages the discourse. It's not helping anyone.
