If your end goal is "get this piece of software out the door as quickly as possible" then yea - drop the ticket into Jira, that's what the business probably wants anyway.
If you want to garner a deeper understanding of a system, exercise your critical thinking / creative problem solving abilities, improve pattern recognition and memorization abilities... You probably aren't going to get that from "fix ticket-1485, no mistakes"
To me, writing code manually really digs into those "critical thinking skills" at a low level - logic bugs, tracing complex code paths, hell even troubleshooting a syntax issue exercises pattern recognition skills.
It's the same reason I don't use LLMs for communicating with other humans. I think that understanding LLM output, crafting a sentence, highlighting the critical points, and using proper terminology in my OWN writing style requires good language skills and keeps me sharp.
To each their own, but it takes 15-20 minutes a day to rock a leetcode problem and is a great way to get the brain moving.
Not sure I get the "you're a dinosaur" approach. Let people handcode if they want, if they're not performing at work they will be put on PIP or fired, or we'll all be out of a job because AI is so good.
