I can just imagine the reaction of a stone-ager being berated because they hadn't come up with "literally just a fatty acid salt with some phytochemicals that have antimicrobial properties". I suspect you could pick just about any tech invented in the last decade and describe it as "literally just a pick-your-adjective noun with some other random nouns that have something-or-another properties"...

Explain again why anyone would stop needing soap? (other than having departed this world...)
