for me, there are tons of aspects of the world that changes absolutely everything in the world all the time. medicine, environment, climate effects, stuff that the James Webb Telescope is observing (for example the idea that the universe is way older than we thought), every single moment we are creating or observing something new and suffering from (or benefiting from) the impacts of what we found or created. If a person wants to go from "I don't know anything about this topic such that a wikipedia article is too confusing to interpret" to "I can understand an arxiv paper and discuss about its significance" they absolutely need to know why they want to do this. There are a lot of topics in the world, and it's past the time where a DaVinci can master topics from anatomy to physical science to philosophy all in one lifetime. Gotta pick and chose, and knowing why is a big part of picking.
