Bring back the old days where we engineered software to be used long term, instead of the current day world of: "Move fast and break things... oh, and don't bother thinking about what'll happen in 10 years, because your CV will be full of bleeding edge stuff, your bank account will be loaded and the troubles with most of the projects behind you won't be the slightest of your concerns."

Rarely are digits tokenized consistently. Because they don’t really know what numbers are, tokenizers might treat “380” as one token, but represent “381” as a pair (“38” and “1”) — effectively destroying the relationships between digits and results in equations and formulas. The result is transformer confusion; a recent paper showed that models struggle to understand repetitive numerical patterns and context, particularly temporal data. (See: GPT-4 thinks 7,735 is greater than 7,926).
