The defining featre of an "exponential" curve is that there is no "bend". The bend is an illusion create by arbitrarily imposed scale. What there is, "quality that matters to to you" and "price you can afford", and you should ignore the part of the curve with too-high price and too-low quality.
Hmm. Don't see that. The defining feature of an exponential is that there is a bend everywhere.
A linear plot has no bend.
As long as my y axis is linear, I can always see a bend in the exponential curve no matter what scale I use on the left, provided you have the correct x axis limits to visualize the bend.
As far as only paying attention to quality that we personally value and is affordable, I agree.
The point is a “bend” implies a spot like an elbow, where suddenly diminishing returns kick in. Exponential growth is a clean curve with no such spots. Move x units right, you’ll always get a y% boost.
