I think what is fascinating about old bikes, and old things in general, is that they were generally crafted with passion and with love. Today, things are crafted with a consumer cycle in mind. You replace your smart phone ever 1-2 years. You replace your car every 5 years or so. Whatever it takes to keep us spending. Sure, technology has improved, and a new bike will definitely have more features than an old bike, but it won't necessarily have that same sense of craftsmanship and pride.
