Remember when people claimed that the bitcoin block size couldn't be increased because we would sacrifice decentralization? Well look where we are now...
~$11,000 a year on GCP according to https://gcpinstances.info/?cost_duration=annually, for just the instance, if you commit up front to a full year. Then add on storage and ingress/egress traffic. And this is without the GPU requirement yet.
Yeah, it's true. The claim/theory/working hypothesis is that technological scaling will reduce the cost of a node over subsequent decades so that running a node becomes more affordable, increasing the decentralization of the network.
