In related news, scientists discover idioms not mathematically accurate. Movie at 11.

It's "film at 11," which used to mean that the news team actually had footage of the news, back before it was assumed that everyone had already seen it on YouTube.

:P

The concept of a "steep curve" is the physical analogy to a steep hill, in which forward progress/learning requires significant effort. Thus x is progress and y is the cumulative effort required to achieve that level of progress.

Right. I suspect the colloquial use keeps "learning" on the y-axis but has "progress" on the x-axis, instead of "training". That is, the psychologists consider learning a function of training, whereas others consider achievable work a function of learning.

Really? I always thought that was what TV anchors said after wrapping the daily news up, i.e. a movie was what was coming up next. However, Wikipedia agrees with you, so thanks for teaching me something!

"The concept of a 'steep curve' is the physical analogy to a steep hill"

Of course it is. That is likely the reason why the meaning got mixed up in the first place. The rest of your comment is rationalization (Otherwise, people would call it cumulative effort curve.). See richardw's sister comment.

Yes, that's exactly what the article said.
