I emphatically do not use multiple agents at a time... I monitor what the agent I'm working with is doing, stop it if it's going down the wrong path and give feedback along the way... don't be afraid to git reset a set of changes, then tell the agent you did so and why. Spend more time on structure and design up front, it will save you a lot of headaches later.
Beyond this, I've found the "5 hour window" that anthropic gives to be pretty helpful... when I've expended my allotment for the window, odds are, I've done enough for the day even. Read, work on something else, etc... know when it's a good time to stop for a day... it's easy to over-work yourself... it takes discipline to actually break for lunch, or the day. For that matter, step away from your desk for lunch and plan to take at least an hour if you can.
You can still deliver a crap ton of value beyond what you individually could do with an agent... but there needs to be a human in the loop for anything that people depend on for their money or livelihood.
And this doesn't cover the scenario of code reviews. If, in the example, Ben and Alice are reviewing each other's code - Ben now has twice as much code to review as Alice does, so her AI usage also affects him negatively.
And I still enjoy the process actually. It's a different process indeed. But times change, and you can't always do the same thing forever.
This asynchronous engineering progress has allowed me to do more householding in between. It maybe sounds crazy, but I feel it helps me organise my life better. For me it won't cause any burnout anyway.
I might be open to some agent-like behavior, access to a git repo and ticket system. Probably not my whole OS, any more than I'd give to a drunk schitzo I met on the Internet.
I see the appeal to what people have going on. But I've been using LLMs for going on a year, I was slow to adopt and wait-and-see because I didn't need it at the time (deep dive, learning python Ecosystem). I'm glad I stayed the course. I can get great results prompting these things and edit the results with care.
No more burnout than a subordinate working for hire in this mode. Things remain manageable, and I can do all the higher level Dev/Eng/Product work that drives the Coding. Which is a good new challenge to me, never got to go so high up the food chain with so much focus.
