I want to see something like Flow integrated into the js specs. Types can help optimization just as they can help correctness!

At least FF devtools show you the event handlers attached to html nodes! But generally I agree with your statements.

I like to break down need of understanding into a few categories:

- no need to memorize or understand (some domain specific and infrequently-used portion of the API)

- memorize and understand later (it's better to just continue and get a holistic picture than to get off into the weeds analyzing how some framework magic works)

- you should comprehend this fully before continuing (general and recurring patterns for structuring your code)

Is it worth it if we exchange 3 drunk drivers' lives for 1 bystander's? Can we really just use a single measure here?

Well, sure. You have your luck as determined at conception, your luck of upbringing, and then your luck as an adult. They're all luck-based, but qualitatively different.
