Capitalism isn't being "destroyed from the inside" by you offloading grunt work to an agent. If anything, you may be helping justify future cuts of your job by demonstrating that there is less need for you. Your managers will be all too happy to cut half your department and make the remaining people take on all that work because, "AI makes them 5x more productive." Of course, none of those people will get a 5x pay raise.

Use it or don't, it doesn't make a difference in the long run. This bubble will pop soon anyways and we'll be on to the next "revolutionary technology." I suspect it will be quantum computing, I've been seeing a significant upswing in news articles and bot traffic about that over the last few months, but who knows.

If your work is pushing AI hard, use it if you need the job, play the game if you have to, just don't let yourself be mesmerized by the aggressive marketing hype. Anybody who is pushing the idea that tech workers will be replaced in the next 5-10 years with LLMs is a religious fanatic and should be treated with the appropriate levels of mockery and disdain.

Also, if you really want to work on taking down Capitalism, organize your labor, and support other movements that do the same.
