I get what you're saying, but I'm not deciding what should and shouldn't count as an alternative to X. I'm trying to answer the counterfactual: how do people behave in an alternative world without Wikipedia but otherwise identical to our world?
Then we had computerized encyclopedias and search engines that searched the library.
I mean, you had to work for the knowledge. Sometimes you didn’t know something and no one else knew either, so you had to wait until you got a chance to find out, but you would think about it and sometimes you would be right when you found a reference source.
I’ll also note, Wikipedia is a secondary source. It is not a reliable source of truth. It is more like the ‘ask someone else’ alternative than anything else, it’s just ‘someone else’ is a person on the internet who writes Wikipedia articles.
