"Wikidata, an obscure sister project to Wikipedia, aims to (eventually) represent everything in the universe in a way computers can understand.

The 30-44 age group was most active with 51.3% daily users. - Consumers over 60 skew significantly toward Amazon Alexa use for smart speakers and Apple Siri on iPhones. Google Assistant and its primary distribution of Google Home smart speakers and Android smartphones are not very popular among older Americans."
