Etymology
This comma was found repeatedly through computer aid, and the name technologisma keeps the connection to technology without adding anything arbitrary. This is, mathematically speaking, a very efficient comma, even if very complex.
It was originally named chatgptsma (and its associated temperament, chatgptsmic) by Praveen Venkataramana and Tristan Bay in 2024 as a joke. Following negative reception from other members of the community about this name, a vote was held to determine a more fitting name. The name technologisma won this vote.
