You may be over-estimating how much money I have as a techie, I work in non-profit/academic sector. My retirement funds are relatively paltry compared to what you may assume about techies with so much money (but perhaps still more than US median for my age; googling says median US retirement savings across all working-age households is $95,776), and mostly in managed 401k/403b where I have previously just chosen "lifecycle funds". ¯\_(ツ)_/¯
People make a lot of assumptions about how much wealth random HN commenters or the HN audience in general have, and sometimes I start feeling like I'm really poor compared to all you techie multi-millionaires... but when I actually pay attention to comments, I realize, nope, a lot of HN is more like me (although probably often ashamed to say so).
