This article points to a common misconception around self-hosting.
The author tries hosting at home for a few weeks, & proclaims it is not the way. They then go on to argue for community managed server infrastructure instead (which is very much self-hosting).
Self-hosting does not solely refer to home-hosting ('on-prem'), nor sole owner-operator. It scales up to server infra in a datacenter, run & governed by those using it
So yes, the future is very much #selfhosted!
