I was hoping for something a bit more surprising in the list, but it's a defensible choice. It's very close to just a list of the richest tech entrepreneurs ordered by net worth, though, with a few swaps and one non-super-rich addition (Gordon Moore).
For reference, these are the top 7 richest tech entrepreneurs by net worth (as per the Forbes 400): 1. Bill Gates, 2. Larry Ellison, 3. Jeff Bezos, 4. Mark Zuckerberg, 5. Sergey Brin, 6. Larry Page, 7. Michael Dell
And this is the "most powerful entrepreneurs" list: 1. Bill Gates, 2. Larry Page, 3. Sergey Brin, 4. Larry Ellison, 5. Mark Zuckerberg, 6. Jeff Bezos, 7. Gordon Moore
