Computers are starting to use staggering amounts of electricity. There is a trade-off here between the utility of the tasks they perform and the climate damage caused by generating all the electricity they need. Bitcoin mining is thought to be currently using 2% of America's electricity and seems an especially egregious waste of energy.

Radically diminishing computer's electricity requirements as they become more powerful should be seen as an urgent task.

Aren't modern computers taking way less energy than before per work? We just keep using more of it faster than the energy use decreases?

Yes and yes
