Far simpler: edge computing is the admission that modern mainframes, the cloud, are untenable, we need local ones. But since few giants do not want giving users ANY IT power and remain in control they offer a middle ground: you buy devices we manage and control, such device act locally as needed, pushing just something to us for our surveillance, in exchange you get "magic services", breadcrumbs of what you potentially can get but since you do not know just obey and be happy, we are the expert you are just a cow with only two legs.
