Well more and more computing power in one place won't be carbon neutral. I disagree with this article. It's like writing that 100 meter building can be more efficient than 100 buildings. Yes it takes less space horizontally but it's more complex to power it and support people then make 100 same buildings and provide each with wind / solar power. That's what decentralisation is about and maybe somewhere in future we start building self sustaining villages with own small networks that barely need to communicate with outside world instead of building giant networks that are inefficient. P2P FTW
