- Many people underestimate the complexity of building large-scale systems like Google Search, assuming off-the-shelf tools like Lucene can easily replicate its capabilities.
- Optimizing performance and adding features (e.g., handling internationalization, security) require significant engineering effort beyond an MVP, often justifying large teams.
- Organizational inefficiencies, such as miscommunication and delays, are far harder to manage than technical problems, making it unrealistic to assume perfect team efficiency.
- Large companies invest in features, security, and sales because marginal gains (e.g., revenue increases from small tweaks) outweigh costs, leading to multi-thousand person teams.
- The misconception that a small team can replace a major service ignores the hidden work like error handling, internationalization, and optimization, which exceeds the core service work.
