The same lesson 30 years ago. WordPerfect insisted that their engineers write code in assembly to achieve maximum performance. Borland did not want to bet on Win32 because they wanted to have the maximum performance under DOS. Lotus-1-2-3 thought that it was ridiculous for Excel to use so much memory and had higher latency on Windows. In the meantime, Microsoft charged ahead with a focus on features and user experiences. The rest is history.
