>> It's too bad people spend energy for generating them now.
How do you mean?
Some quick back of the napkin math.
Creating a 'throwaway' banner image by hand, maybe 15 minutes on a 100W CPU in Photoshop:
15 minutes human work time + 0.025 kWh (100W*0.25h)
Creating a 'throwaway' banner image by stable diffusion on a 600W GPU. In reality it's probably less than 20 seconds to generate, but let's round it up to one full minute of compute time:
5 minutes human work time + 0.01 kWh (600W*(1/60)h)
The way I see it it seems to spend less energy, regardless of whether you're talking about human energy or electrical energy. What's the issue here exactly?
