I know a guy, he worked at MSFT, and we worked together at FB. Combined he had 10+ yrs of tenure and at one point he was L8 I believe. I assume he has $10m+ net worth. He "quit big tech" and now has a non-profit startup, with funding from a philanthropic tech foundation. That seems like a good way forward, you can continue working in technology and code, it's exciting bc it's a startup, there's social good, but with the funding you can pay yourself a salary so you're not burning your net worth (which is invested and cumulating presumably), and since you're already rich you don't mind if it's non-profit.
