Is There a Flaw in the Spa Architecture?

Ajax is a way of making data fetches happen close to the server, and then all this now streams down to the client. And so the client just kind of acts as like a dumb render of a components that were generated on the server. This isn't really a problem that we face in our aps, not because our apts are immune to this problem. But i think this is a nice answer that rea can give and say, ok, this is how we cann conceptually think about this.
