What is the most logical explanation why there is no denim in the science fictional future?

1. Denim is stylistically associated with the recent past (specifically, the 70's or, if acid-wash, the 80's), so it is generally avoided when constructing a fictional future.

2. The amount of spandex in jeans these days is increasing to make for tighter and more form fitting clothing, in the next 2000 years this trend takes off and the amount of spandex increases until we are all wearing the kinds of spandex bodysuits that are more common in scifi Tl;dr: blame skinny jeans

7. Nanobots. A technological breakthrough allowed fully sentient Nanobots to reduce the plight of the hungry, poor, and sick. They worked at a miraculous pace and changed the face of society worldwide. However, this came at a cost. The Nanobots had one fatal flaw; an insatiable hunger for denim. At first, the scientists and engineers didn't notice this issue because so few of them wore denim, but as their usage grew so did the apparent cost of doing business. It was agreed that the best course of action was to simply placate their desires by allowing them to feast on denim which would be manufactured and imported from all over the world to the Nanobot home base. However, as the Nanobot Society grew, so did their demand. It became too much for denim manufacturers to keep up with and soon rogue Nanobots were devouring denim from within peoples closets and wardrobes and even going so far as to eat the denim right off of their bodies. A brave young Danish engineer, Hans Florenheim, came up with a solution which would rid the world of the Nanobot scourge. Thankfully, the improvements the Nanobots had made to the scientific and medical communities had fostered permanent lasting changes to the world at large, reducing societies dependency on them. Once the Nanobot Solution was deployed, a large scale micro-EMP attuned to a unique Nanobot brain wavelength was able to permanently destroy all the Nanobots in existence. Over time, the world moved on, vastly improved in many ways and capable of prospering in the light of a new future filled with hope, but Denim was never produced again as a sign of solidarity against the plague that had very nearly destroyed the fabric of humanity itself.
