As a developer, on my very best days I probably spent no more than 50% of my day actually writing code. So call it 4 hours of actual hands-on-keyboard coding.
But AI can write code much faster than a human. In 4 hours it might be able to write what would have taken me a week. Or more. Assuming it had proper specifications for that volume of code.
Typically it takes me as long to review code as it takes me to write it myself. The exception is repetitive coding tasks that cause my attention to drift, which LLMs can do very quickly.
