Obviously the average tech person can't retire with 50 while living in a golden castle. Nobody claimed that. If you retire that early then you lifestyle needs to match your wallet. I'm not even 50, I'm just below 40, but I could retire tomorrow despite not having worked at Google or similar. Obviously I couldn't own a 1500sqft condo in downtown SF, drive a big car and go on a yacht vacation in Monacco every year. But I could afford a nice place in the countryside and continue with the hobbies I have, none of them demanding big financial resources. It's about lifestyle choices, no matter how much money you have.
