The lower bound is certainly lower than 3x. I do very domain-specific work (in Rust/Python) and usually the output is useless and ignoring the garbage suggestions can have a higher mental load than not using it. It does work well for boilerplate though and since boilerplate is the most annoying code to write, I'll tolerate it. I agree that the upper bound is pretty high, with more straightforward MVPs, it can generate large swabs of code for you from a description. Also for little DSLs that I haven't memorized, generating a pyproject.toml from a bunch of constraints is so much nicer/quicker than reading the docs again every few months.
