The reason Leica has survived is because it successfully transformed itself into a luxury brand.

Artists and philosophers need to sell aesthetics and philosophy in order to survive.
Aesthetics and philosophy alone are useless, but they are essential parts of luxury products.
People disdain poor art, but highly value expensive art.
The perception created by pricing becomes part of the product.
To some extent, artists have to maintain nobility and elegance.
The value of artworks does not solely come from themselves but also from their pricing.
Moreover, luxury goods must package artistic aesthetics within practical, functional products.
Hermès transitioned from harnesses to handbags and scarves,
Louis Vuitton shifted from hard cases to handbags and ready-to-wear,
Leica survived by relying on lightweight integrated cameras (the Q series is Leica’s cash cow),
while Hasselblad’s medium format cameras are too specialized to reach the mass market.
From this, I can conclude:
Luxury goods are the productization of art and the functionalization of craftsmanship.
