It is a list of wealth created for index funds, pensions, employees and co-founders, not the overall benefit to society.

A more serious ranking would probably be dominated by these groups:

* Agricultural and public-health innovators - affecting billions of people at low cost - Louis Pasteur, Norman Borlaug, Fritz Haber and Carl Bosch, followed by sanitation engineers, vaccine developers and epidemiologists, then the myriad of scientists/engineers responsible for clean water systems

* General-purpose infrastructure creators - electricity, semiconductors, refrigeration, telecommunications, etc... - Faraday and Maxwell

* Open standards and open-source creators - Linux, Git, FFmpeg, TCP/IP, HTTP/HTML, Python, PostgreSQL, etc - they repeatedly eliminate costs for millions of organizations. Richard Hipp created SQLite that is embedded in millions of phones, browsers, apps, OSs, ... - Claude Shannon, Tim Berners-Lee, Linus Torvalds

* Institutional and conceptual inventors - double-entry bookkeeping, randomized clinical trials, peer review, container standardization, cryptography, etc - reducing transaction costs and increasing trust across the world.
