Estimation case: size the market opportunity for Google Translate

How large is the total addressable market for Google Translate? Walk me through your estimate. ```hint Decide who pays Most people use Translate for free, so settle who would pay for translation, and in what unit, before you start multiplying. ``` ### Clarifying Questions - Should the market cover only the free consumer product, the paid translation service for businesses and developers, or both? - Do you want the answer as yearly revenue in dollars, or as a number of users? - Is this global, or a single region? - Should translation work that is paid to human translators today count as addressable? ### What a Strong Answer Covers - A clear definition of the market: who pays, the unit, the time period and the geography - An equation split into segments that differ in how they use or pay for translation - Every input labeled as an assumption, with round numbers and the arithmetic shown - A sanity check against an independent reference point - The gap between the total market and what Google could realistically win, and the inputs that move the answer most ### Follow-up Questions - Which assumption changes your answer the most, and how would you get a better number for it? - If large language models push the price per character toward zero, what happens to this market in dollars and in volume? - The largest customers often build their own translation systems. How does that change the share Google can actually reach?
