Alternative take for this same sentiment: It's the year 2021, why has nobody figured out better ways to present knowledge than simple text files?
But (afaik) nobody's selling a product that builds and queries a large semantic knowledge base for consumers. Some industries have Semantic Web-based solutions (i'm not aware of commercial ones but I assume they exist), but nobody has yet explained to the consumer why or how they should build ontologies or keep data in triples. The terminology itself is probably a barrier to market, and all the interfaces are (imo) clunky.
If I were to build a consumer product, I would hide all the technical jibberish and make a slick UI that walks the user through linking semantic data, leaning heavily on Wikidata to fill in gaps. Gameify it so that people can compete for points to link more data, add a subscription fee, add social components: poof! Billion dollar personal-knowledge-base app to replace Evernote. Value add/tagline: "Know yourself better." (inb4 selling the free version's users' anonymized data to advertisers...)

There are a plethora of alternate ways to represent knowledge. Each has its own set of trade-offs. Which do you prioritize?
Ease of editing Interoperability/readability in multiple systems Expressive styling Optimized for configurations Optimized for readable text Etcetera
Fill out that list, stack rank it and tell us which format is better.
I know, we don't get many of these in this field anymore. I think this means something.
