This is a great write-up. And a bit generous to the "developer" in question.
I'm not entirely sure I've written 250,000 lines of code yet, in my entire decades as a professional developer. If I have, it's a near thing.
Not to brag, but I can reuse existing libraries and get many things done with 5 or 10 lines of code.
It's hard to crack 250,000 when 5-10 lines solves each of my employer's problems.
And this young developer supposedly solved one problem with 250,000 lines of code.
After giving it some thought, I'm like 90% 40% (edit: okay, 40% after hearing some anecdotes, haha.) sure this is just a parody post. Even AI can't be that bad at this, right?
