What a super weird question. "Cloud computing" is distributed computing. Distributed computing is practically all we have left. Bitcoin/crypto, Kubernetes, Bit Torrent, and endless AWS/Cloud infra patterns. Then we have our happy little Fediverse here.
I feel the author was trying to say "is at home distributed computing dying?" In which case, yes, because Mobile took over and you really can't do background compute on those. Certainly not like how SETI@Home worked.
