Since starting to use LLMs, I have actually been spending more time, at the console, than before.
One reason is that I like to ship (as opposed to "code"). That means a lot of tedious, boring stuff. The kind of thing that I want to "take a break before tackling," so I may take 30 minutes, and watch something on TV for a while, before rolling up my sleeves.
Now, the LLM can take care of a lot of this stuff, so I am not motivated to "take a break," so much, anymore.
It doesn't actually feel bad, but I now have to schedule "downtime." I never used to have to do that, before. My work always involved a lot of "context switch" points; naturally set up for taking breaks.
