[The]
junk merchant does not sell his product to the consumer, he sells the consumer
to his product.

He
does not improve and simplify his merchandise. He degrades and simplifies the client.

*The following article, unlike the one above, is not primarily intended
for mathematicians, and should not be read as a history of p-adic Hodge theory
and perfectoid geometry, much less as a rigorous account of their mathematical
contents, which I am thoroughly unqualified to produce. I nevertheless apologize to colleagues
who feel their work has not been given its proper attribution. A more detailed clarification can be
found here.*
