A Semantic MediaWiki page on a site called Platform Docs, titled Meridian Falls. The upper code block shows the wikitext source with two parser calls, property_link and set with a +display option; the lower block shows the rendered sentence 'Meridian Falls has a population of 812,405', where 'population' is a link to the property page, with a Facts box below listing Has population 812,405. The intro line reads: Store and show a value in one #set call, and link to a property from running text, since Semantic MediaWiki 7.2.0.

In the age of AI, comments that explain what code does are even worse. Before AI, you'd already want to avoid such comments in favour of self-explanatory #CleanCode. Comments can drift and be wrong. AI can cheaply explain code. Comments that cache human thought are now doubly not needed.
