Thinking laterally for a moment regarding the big picture here, why do we still rely on data centres.

They made sense in a world of dialup and low speed / high latency broadband. But there are lots of places with high speed fibre and not much latency to the peering points.

And the more we break away from data centres and clouds, the more the internet infrastructure will have to work the way it was designed instead of having to flow through these crazy aggregation points that are both serious points of failure and major security risks.
