When you say, "compete," what I'm reading between the lines is, "compete on
dynamic range, noise, and number of pixels."
There are more dimensions than that, such as cost and power consumption.

According to farm scientists at Cornell University, cultivating one hectare of
maize in the United States requires 40 litres of petrol and 75 litres of
diesel. The amazing productivity of modern farm labour has been purchased at
the cost of a dependency on oil. Unless farmers can change the way it's grown,
a permanent oil shock would price food out of the mouths of many of the world's
people. Any responsible government would be asking urgent questions about how
long we have got. -- George Monbiot
