One can simultaneously be impressed by the engineering while wondering if this level of custom implementation at what will probably be pretty low scale really makes sense.
Bezos's proposition needed to be qualified for each customer; in some cases, he was wrong. Yes, sometimes renting other people's hardware makes sense, for a time, until it doesn't.
I wrote 'proposition', not 'fact'. Jeff made a simple proposal, then I, as the customer, can evaluate it, accept it, or reject it. 0xide doesn't have a simple proposal. They have a constellation of nitpicks and tastes, but that's not good enough. The typical consumer in this space wants quantifiables.
