I have run llama.cpp on an i7-2600 with a 1050. It's too slow for everyday usage but it's not too slow to make it obvious AI is going to be everywhere and in everything. It's too easy to run.
Try pomodoro instead. It's 25/5 work/break. I started out with 60/15, then 45/15, then 25/5 and found out they were right. These breaks, for me, are just walking elsewhere to do a household task and then coming back. For most, it's likely all you need.
Yes, some people, particularly coders, are exactly like that, especially when they're young and everything feels like it comes easily. Young coders can sit for hours on a single task if they're really into it and make good progress. As you get older, and the cognitive load increases, you're forced to find out what you did before doesn't work anymore.
Can confirm. Pomodoro is an essential productivity and creativity hack. We coders always knew it was true, that your breakthroughs come from walking away from your work, but until you find something like pomodoro you don't realize this is a great habit to normalize. It even works for the shortest breaks.
