Much as renewables are most efficient in a grid, hardware is most efficient in a data center.
Can we distribute and become autonomous in both? Yes. Do the times hint we might have to? Also yes. Is it optimal? Not really.
When you self-host, your hardware sits mostly idle, waiting for you to need it. In a data center, that same piece of hardware could serve so many more people, each with their own schedule. The data center approach is more environmentally sustainable, as it makes better use of the hardware, and so requires much less of it for the same output.
Unfortunately, though, there are also big, huge externalities. Dependency. Abuse. Roadblocks. Advertisement economy. This is what mostly drives people to owning their own data and infrastructure. It’s not a bright, perfect future for everyone. It’s a necessity of time, not a perfect solution. Granted, it might be fun to fiddle around with.
That said, I do self-host, and I do own my solar panel. Such are times!







True! Some level of distribution is essential for the resilience and doesn’t eat too much of efficiency.
In fact, I’ve been contemplating on the possibility of small, neighborhood data centers. They could both reliably provide local information services, as well as on-demand computing power.
