That's a 50% time reduction for the same output which sounds great to me.
I'd much rather let an LLM do the menial shit with my validation while I focus on larger problems such as system and API design, or creating rollback plans for major upgrades instead of expending mental energy writing something that has been written a thousand times. They're not gonna rewrite your entire codebase, but they're incredibly useful for the small stuff.
I'm not even particularly into LLMs, and they're definitely not gonna change the world in the way big tech would like you to believe. However, to deny their usefulness is silly.
