Cost optimization IS the limits of the technology. All the nice things you mention are the result of large amounts of work by exceptional people. This costs money. Most of them require higher-spec components, or more design time, or more complicated fabrication and assembly. These things also cost money.

Nobody's denying you nice things at low prices just out of spite. Nice things just cost more. To put a positive spin on it, our innate sense of 'nice' is a well tuned heuristic for good engineering (and/or whatever the Joneses can't afford).
