Haha, that's an interesting thought. Not to play devil's advocate, but can you honestly tell me the average American's weekly car need couldn't be met by a horse? (Mostly kidding.)

I think the distinguishing thing here is that those technological innovations were all adopted voluntarily by people setting aside the previous technologies, for the advantages of the new technology were obvious. Here, people are clinging to the old tech despite being threatened with its constant depreciation (already done on Apple systems), for the simple reason that using the new tech is more work for no more gain. For the average use case, Vulkan feels more like a technological regression than an advance.
