I think you have a lot of questionable assumptions, which leads to your original question.
First, at 50 my brain has not 'slowed down'. Nor has my zeal for new tech, learning or stamina.
Made it big? Not sure what you mean by that, but I've had a very rewarding career (almost 20Y in the same place) that has provided me consistently with challenge and success.
Last thought, I'm part of a team of devs in our early fifties. I feel like with our experience, maturity and honed skills we could wipe the floor with a team in their twenties if we wanted. Might just be us. Just MHO though.
