Commoditization is the right word to use imho. I think OP is using it here in more broadly philosophical (marxist) sense; a reductive process which makes mass manufactured products essentially interchangeable in the market. The only differentiation that can arise then in is in terms of branding. That's exactly what cars are now. Identical metal boxes, captured by marketing, purely differentiated on intangibles like brand identity. And even this differentiation is becoming less and less relevant. How many people still really care about their cars? (mostly men do, and even that's waning). They're basically washing machines now.
