> A city census tract was considered “middle income” if its average per capita income fell between 80 and 120 percent of the metro-wide average for that year
The "middle class" term should be replaced in our language with something more concrete. It's not even a class after all. It's just an arbitrary label that doesn't have any useful meaning.

I haven't used SuperMemo (the app that inspired Anki development), but looks like it has all these features plus tons of other stuff (https://help.supermemo.org/wiki/Incremental_learning). It has some flaws (not cross platform, doesn't support PDF directly, complex UI, and of course closed source), but I think it's unfair to claim "a new class of application".
Everything new is inspired by something in the past. Literally nothing comes from whole cloth. I think the point I was trying to make is that we're going to see more of these types of apps.
> if one candidate is willing to do more work ... that's one person showing they are willing to put more effort into a job than another
I'm not happy with this logic. It's harmful. If you extend it further, it motivates everybody to work more hours too.
"If a person is willing to put more effort into a job than another let him do that! Oh and by the way, let's fire those who are not and hire those who are".
And we're back to 12+ hour work day and a lot of great specialists are out of their jobs or forced to sacrifice their time with families, friends, hobbies, physical activities, etc.
There are ways to conduct interviews without whiteboarding AND without take home assignments.
