Where do you see an exponential curve?
The article doesn’t discuss any exponential decrease for a reason. And most of the “dramatic drop” looks like it happened in the first 10 years
Time is running out.

- melling 4y ago“Between 1991 and 2018, the average price of the batteries that power mobile phones, fuel electric cars, and underpin green energy storage fell more than thirtyfold” THIRTY FOLD ISNT EXPONENTIAL. Please reevaluate the plan. It likely contains a lot of optimism and a few required miracles
- evilsetg 4y ago> THIRTY FOLD ISNT EXPONENTIAL. A * exp(b * t) = A / 30 => b = - log( 30 ) / t As far as I can see a thirty fold decrease does fit into any exponential curve if you have the right rate constants or times, so I don't really get what you mean with that.
- epistasis 4y agoThe data is right there, it's on an exponential cost decrease. Very weird to be pointed directly at the data and deny that it says exactly what it says. You say that "nobody likes to be proven wrong" but I in fact do like to be proven wrong. The "nobody" appears to only apply to yourself.
