If that study is the only thing you have as an argument you won't get very far (though it is worth it to read the thoughts of some of the participants: https://domenic.me/metr-ai-productivity/).
It is very helpful to me as a developer: I can now write entire custom tools, one-off scripts and services for myself I otherwise wouldn't (because it would take too much time and too much effort), it catches a lot of logic bugs in code reviews as a first pass, it's good at generating unit-tests, etc, etc.
But coding is not all there is. To me as an immigrant, AI-based translation is a godsend. Same for writing scary-looking letters to government officials or applications for apartment viewings. Same for learning a language, actually. When I was looking for a new job - I used ChatGPT's automation to filter out crappy job postings and parse feedback on Glassdoor for the interesting ones. Like, genuinely, if we imagine for a moment that there's zero moral and environmental issues with AI and you still can't think of any possible applications of it for yourself you're either just not doing anything or you're dead.
