I know, I was mostly interested in capturing the "amounts to" of what he said, as opposed to the precise words.

That some decisions are more important to get right than others (that "the dichotomy exists"), is just a trivial observation, the kind that people like Bezos make to appear insightful "technical leaders", but which are ultimately empty, amounting to "some decisions are important, others are not". Gee, thanks, Jeff!

The interesting part is knowing which case is which, or advice for that - which the above leaves out.

I read it as "some decisions end up being more important than others, with no way to know beforehand, keep trying things to increase your luck surface".
