>We have far more computers then a decade ago,

Yes that was already taken into account. We rushed pass active usage of Smartphone of 4B in 2020. With additional 1B user who have access to 4G / Smartphone but not using any Data. 1B people who cant afford it or are using feature phone. And around 1B people who are outside the age of using smartphone, child, baby etc. That is a total Around 7B people already. And anything after is a long tail of new generation outpacing older generation. Tablet usage has levelled off. PC market hasn't had new growth outside China and India. COVID managed to fasten a lot these digitalisation. I wrote about how the Growth of AWS in 2023 was roughly equal to doubling of itself in 2016. i.e 2023 AWS was building out the size of AWS 2016. That is insane. And yet we are still building more.

>Another thing which people seem to not notice is that a lot of older DC's are being phased out,

That is something I am not aware. But certainly will keep a look out. This got me thinking if building out a new DC is easier and cheaper than repurposing older DC not designed for high computing power density usage? While I have said we could increase Compute, RAM , Storage density in Rack by 10-20x, we have also increase power usage by 4 - 5x. Not only electricity / power usage but cooling and design also requires additional thoughts.
