I'm not saying it's a linear function either. I think it varies. But I also don't think the value added per unit of resources used is growing exponentially. So the problem still remains, because anything short of exponential function isn't going to impact the overall trend long-term.
>value added per unit of resources used is growing exponentially
I would love to see the amount of resources that are used to produced each iPhone, because I don't have a big issue assuming that each phone brings, say 3 or 4 percent more utility to its user than the previous model would have.
So, assuming the battery is the most dirty part of the phone, I found the battery size for all the iphone models[0] and even if we exclude the the large ones, the iPhone 11 has a 54 percent larger battery.
The phones were released in 2007 and 2019, 12 years and 3 months apart[1]. That works out to a growth of approximately 3.3%.
So my original assumption was wrong, there has been an exponential growth in materials that nearly matches GDP growth.
