Ebbinghaus didn't integrate areas under the acquisition curve. He wasn't a mathematical psychologist.

Whatever that is, it's not a learning curve. Ebbinghaus defined it in his classic work.
That's where the confusion comes from, conflating the experience of walking up a steep hill vs an acquisition curve.
I thought that was a civil statement. I may be miscalibrated but I thought it was among the mildest of four letter words. I'd be happy to extend my vocabulary in the gentle art of dismissal.
I have given up on "steep learning curve". A learning curve is proficiency on the Y axis against time on the X. A steep learning curve indicates something that is learned very quickly. A shallow learning curve is something that takes a long time to master. See Ebbinghaus 1885.
Are you my brother-in-law?
Get bent. Impacted is absolutely acceptable usage to describe a direct or follow on affect from an action or initiative. It's useful precisely because it's an intensifier that conveys not just that there is a detectable change in an indicator, but there is a major change that directly attributable to the manipulated variable.
I've seen children selling gum in Tijuana but not matches. Bars gave them away last time I was there. Which was over 20 years ago to be fair.
The comment that stood out to me was someone saying "but that was 44 years ago". I was a teenager then and poor people didn't sell pencils on the street in 1980 either. It was an old trope from the 40s? 50s? Much like I've never seen an organ grinder with a monkey or poor children selling matches.
Because it's financially supported by foreign actors?
This drives me nuts too, but most of them fall into one of two categories. They are either B2B so don't care about individual consumers, or they are "lifestyle" businesses with basically one employee who doesn't or can't work excessive hours.
