I'm surprised that, as a senior, you're able to offload your work to Cursor. Maybe it's light years ahead of GPT, but I'm also a senior engineer and get almost no usable code out of AI tools without having to double check and then reimplement its suggestions. I use them to generate ideas for algorithms mainly, and would not (could not) just copy-paste its solution into my/our codebase. It must depend on what you're building.
