Exponential graphs do not have "a region in which it begins rapidly increasing." The differential of e^x is e^x! Across any range of x values, it's possible to choose a scale of y values that shows the classic shape of the exponential graph (ie, the hockey stick). If you then zoom into the flat part of the graph, and choose a different y scale, you'll see a bend there. If you zoom out and choose a different y scale, you'll see your previous bend as part of the flat part.
Unless there is a natural and obviously significant range of y values that, independent of the mathematical properties of the graph, is clearly what you actually care about, you can just make the "bend" in an exponential graph be anywhere you want it to be.
Here is the graph of e^x from 0 to 10, showing the "bend" is at around x = 7. https://www.google.com/search?q=graph+of+e%5Ex+from+0+to+10&sca_esv=8ea0361af31360af&sca_upv=1&sxsrf=ADLYWILfr0kgB4okSkZ1j7gfeKB3Ti_hvA%3A1717657063276&ei=511hZrzMEPWuptQP9pGV-As&ved=0ahUKEwj82-iYs8aGAxV1l4kEHfZIBb8Q4dUDCBE&uact=5&oq=graph+of+e%5Ex+from+0+to+10&gs_lp=Egxnd3Mtd2l6LXNlcnAiGWdyYXBoIG9mIGVeeCBmcm9tIDAgdG8gMTAyBBAjGCcyCBAAGIAEGKIEMggQABiABBiiBDIIEAAYgAQYogQyCBAAGIAEGKIESP8JUMoGWMoGcAF4AZABAJgBiwGgAYsBqgEDMC4xuAEDyAEA-AEBmAICoAKVAcICChAAGLADGNYEGEeYAwCIBgGQBgiSBwMxLjGgB98E&sclient=gws-wiz-serp https://www.google.com/search?q=graph+of+e%5Ex+from+0+to+10&...

- tempestn 2y agoLet me rephrase. Any exponential with a defined beginning and end point - ie any that we are considering over a particular time series - will have a region at which it appears to rapidly increase, before which it appeared relatively flat. For technological progress of humanity up to present day, that region was around the IR.
- aetherson 2y agoI mean, sure, as long as the operational term is appears to rapidly increase and appears relatively flat. If per capital income roughly doubles every 30 years or so, and that's an iron law of nature throughout history, and you make a graph that ends at 1700 and puts the income of someone in 1700 in the upper right, you'd be saying, "Oh man, what weird thing happened in the 1500s/1600s that led to a big change in incomes then?" And if you make that same graph in 2200, the Industrial Revolution will be part of the "appears flat" graph.
- tempestn 2y agoYes, agreed. That was actually my original point, that maybe the Industrial Revolution looks like a special period in history from the perspective of today, for that reason, but in reality it's just a period along a long-term exponential.
