Others may not know the origin of &c., so it's great that you explained. But here's a thought: Abbreviations are not about saving time typing for me. Other reasons for abbreviations: 1. Abbreviations, acronyms, and initialisms are a kind of jargon that compress long words into single tokens that communicate something in a single chunk. That is more efficient for _readers_ to parse... If they are in the know. 2. Speaking of being in the know, abbreviations, acronyms, and initialisms communicate which tribe you belong to, and this strengthens social bonds between writer and readers. 3. Some mediums have limited space available. Newspaper headlines, SMS messages, and the original Twitter tweets are examples of mediums with limited space. Abbreviations help compress longer messages to fit the medium. I happen to be a very slow author compared to just about every professional I know. Since it takes me a while to think about what I write, I find that trying to find shortcuts is not helpful with code or the written word. Cheers...
