I'm convinced the "craft beer" industry settled on IPAs not due to genuine consumer demand, but rather manufactured demand for IPAs because IPAs are more tolerant of faults in the brewing process and therefore have lower production costs (less wastage.) This is because when an IPA turns out particularly poorly, it can be bottled anyway and if anybody points out that it tastes like silty skunk ass (all my homebrews, BTW) some nearby IPA enthusiast will be sure to scoff that the complainant just can't handle the hops.
