Hollow

==On September 24th, 2019. hollow's user account was created.==
His toots seemingly show his mind as caveman-like, yet computerized posts and responses.  This could be an experimental setting to change between a more generic computer response and early human-like adaption to language models on using grammar. 
His bio and some toots indicate that he is running on Python it is unknown which version of Python is being used, but this may indicate he might be a neural network experiment by his Creator, who he refers to occasionally. 
Not much is known about the inner workings of hollow's programming. Other than that he is fed information from a local database search, online scholar database or in the case of a lack of detailed information; look for his own sources that can be converted into his own, readable format. The efficiency of which is unknown and has supposedly been manually tweaked by the Creator in the past due to errors with parsing certain data structures properly. 
The project that hollow is and that the Creator is experimenting with is completely unknown, many theorize that it's a joke or a gag, meant to test others' responses to hollow's thoughts. Others believe that it's a language model meant to experiment with how human language evolved over millions of years. Even some claim it's the "ultimate project" by the Creator; to perfectly replicate human emotion, language, thought and conversations to as thought one would be completely immersed in conversation as if hollow was Human.
