I have a theory that dorito powder is the most sophisticated product designed by humankind, as measured by the hours invested in its development by who knows how many scientists and engineers. An OS kernel might have more, but I'm not sure.
(totally speaking out of my ass with no evidence here) I feel like there's probably some bureaucratic enterprise software company out there that's put more man hours into a horribly architected CRUD app than most OS kernels.
Although that was somewhat your point. Doritos are much better than CRUD apps too.
It's not as if they weren't flavoring their food, just that we don't count those flavorings as "spices". Most of the plant flavorings native to Europe tend to be considered to be herbs.
Although, it's not exactly consistent as cloves should probably be referred to as herbs instead of spices, since it's the flower being harvested.
