The evolution of products is:
Modyfing a basic idea (formula)
Bringing the next iteration (generation) of a product.
a little evolution to start the next cycle and sell again.branching out into many variations, a few survive, become bigger and thus the basis for the next generation. what works stays. what doesn’t improve dies.
example smartphones, changes to the next generation are minimal, fast cycles.
its surfing the fractal line.
basically the modern economy is a self-sustained fractal zoom.
