I think the same about old people btw. we branch their value out to an old value that is not compatible with the values in our current system. Oh boi, we do that so wrong, it's laughable and very sad at the same time how our society thinks about old knowledge, old people etc.
I think HN is the community that most loudly would agree with new != better but that's exactly what we do wrong. Holy cow, I can't explain how much value we have at our disposal that we throw away + pay to keep it away comfortably. New businesses don't integrate old people, because they don't really know how to make value out of them. That's a simple equation, if you see it this way. It's not because old people cannot contribute to the development of IT, Startups and the Hacker scene. We just have no business model, not even a concept that considers these elder men and women.
